And when you're on your own there is that terrifying possibility that you may be the only person on the planet who thinks it's funny - and you have no way of finding out.
This experience actually means the very opposite: the largest military power was unable to stop such a sensitive attack and will be unable to rule out such a possibility in the future. Precisely this is the background to the United States' military interventions.
Invincibility lies in the defence; the possibility of victory in the attack.
My four years in Russia end, then, in dramatic fashion: with a textbook Soviet-style expulsion. I am the first western staff correspondent to suffer this fate since the end of the Cold War. I'm stunned. But my expulsion is not, I reflect, a surprise. It's something I have always accepted as a real, if far-fetched, possibility.
The main thing that gives me hope is the media. We have radio, TV, magazines, and books, so we have the possibility of learning from societies that are remote from us, like Somalia. We turn on the TV and see what blew up in Iraq or we see conditions in Afghanistan.
I think people get a sense of possibility when they're on a plane, even romantic possibility, wondering if the perfect person is going to sit down next to them or something.
The mere thought hadn't even begun to speculate about the merest possibility of crossing my mind.
Opening day. All you have to do is say the words and you feel the shutters thrown wide, the room air out, the light pour in. In baseball, no other day is so pure with possibility. No scores yet, no losses, no blame or disappointment. No hangover, at least until the game's over.
The possibility of divorce renders both marriage partners stricter in their observance of the duties they owe to each other. Divorces help to improve morals and to increase the population.
It didn't seem remotely possible. I had no idea how people got those jobs, I didn't know what the steps were, it never even dawned on me. It seemed so outside the realm of possibility.
I kind of like the idea of living a rather ordinary life as a shopkeeper, and I examine that possibility as one of the outcomes of the young Gerald Bostock growing older.
And I'll never forget the first time I took the possibility to project sound every day for six or seven hours with special devices which were built for me.
Think of all the mesquite in Texas, the pinyon pines, the acorns in Appalachia, every place has the possibility of mass production. It's an infrastructural system so nestled in ecology, it's a more beautiful ecology.
Towards the end of 2003 it was hard to get through training - and the darkest point was when a doctor told me there was a possibility I could end up in a wheelchair.
I cannot be much pleased without an appearance of truth; at least of possibility I wish the history to be natural though the sentiments are refined; and the characters to be probable, though their behaviour is excelling.
In theory there is a possibility of perfect happiness: To believe in the indestructible element within one, and not to strive towards it.
So this is the space during tutoring hours. It's very busy. Same principles: one-on-one attention, complete devotion to the students' work and a boundless optimism and sort of a possibility of creativity and ideas.
Right now women are using surrogates because they can't be pregnant. What worries me is the possibility that soon they'll use surrogates because they don't want to be pregnant.
As soon as you judge communication a little more rigorously, there is a possibility that the message will not be democratized. I have to say what I believe to be right. I have to spread out the statement among all the means of expression available to us at present.
To get art nowadays, in cinema or books or anything, that grapples with the possibility of a meaningless universe... it just doesn't happen any more. In even the most indie of the indie films, everything has to come to some kind of neat conclusion.
We would fight not for the political future of a distant city, rather for principles whose destruction would ruin the possibility of peace and security for the peoples of the earth.
Abroad, they have covered pretty much all subjects, explored every possibility, every twist. So similarities between ideas you have and those filmed abroad are quite possible.
The first duty of society is to give each of its members the possibility of fulfilling his destiny. When it becomes incapable of performing this duty it must be transformed.
Dreams are where we visit the many lands and landscapes of human possibility and discover the one where we feel at home. The great religious leaders were all dreamers.
There is a possibility of fresh talent coming to work for the government. Millennials are the most public-spirited generation since the 1960s. There is an opportunity to harness that generation and make government service cool again.
The search is what anyone would undertake if he were not sunk in the everydayness of his own life. To become aware of the possibility of the search is to be onto something. Not to be onto something is to be in despair.
Drawing is the honesty of the art. There is no possibility of cheating. It is either good or bad.
I saw 'Hamilton' when it was at the Public, and I just wept profusely in my seat because this is a form I love deeply, and to watch it be reinvented in such a genius, gifted way and executed by such a brilliant company of human beings, I was overwhelmed with not just appreciation for the piece of work itself but for the possibility.
I wouldn't discount the possibility that the Israelis would act if they came to the conclusion that basically the world was prepared to live with Iran with nuclear weapons. They certainly have the capability by themselves to set back the Iranian nuclear program.
The weapon of suicide bombing is so desperate that you aren't even left with the possibility of taking revenge or punishing anyone; the terrorist is killed along with his victims, his blood mixing with theirs.
As fears about the energy and environmental crises reach a fever pitch, we're all searching for solutions. And one possibility is that we could fix everything if we'd just shrink our population back down to about 2 billion people - which would put us roughly where we were at 80 years ago.
This is the paradox for me: in failure alone is there any possibility of success. I don't think I'm alone in this - nor do I think it's an attitude that only prevails among people whose work is obviously 'creative'.
However, when my parents married in 1945, China was in turmoil and the possibility of returning grew increasingly remote, and they decided to begin their family in the United States.
Being-alone is a deficient mode of being-with; its possibility is a proof for the latter.
The purposeful restriction of knowledge has been at the heart of untold misery and hardship in this world. Serfs were kept illiterate so as to not jeopardize the feudal system. Slaves were kept in the dark on a variety of subjects so as to not provide them the possibility of escape.
Where ignorance is our master, there is no possibility of real peace.
