At a bat mitzvah over the weekend, and happened to be placed at a great table, with some close friends, and other people I want to know better. I don't know exactly how the conversation got there, but I discovered, at one point, that the women to my left and right, like me, bite their nails.
I have to find out if the other two women at the table do as well.
Perhaps this will be my new criteria for choosing friends.
