The Sharks step right on each other's questions, and if I ever did that in Silicon Valley, I would be considered a pariah. I literally had to learn how to interrupt.
I have a lot of faults. I often interrupt in meetings. I talk too loud. I talk too fast.
When I go to a library and I see the librarian at her desk reading, I'm afraid to interrupt her, even though she sits there specifically so that she may be interrupted, even though being interrupted for reasons like this by people like me is her very job.
