It began with a phone call offering me a postdoc position at the University of Chicago, and inviting me to visit. Not for an interview, since they had already made me an offer, but to help me decide whether to accept.
They put me up in a beautiful suite at the historic Quadrangle Club. Felix Browder, the department chair, took me for a lovely meal in the Club's elegant dining room.
Just before my talk, my host, Niels Nygaard, asked if I'd like some water. When I said yes, Niels went away and came back with a glass of water with a slice of lemon on the rim. I exclaimed at what a nice gesture that was, and he told me it wasn't him, it was the secretary. She had met me and liked me, and wanted me to take the job. I'll always remember that lemon slice. Sometimes it's the little things that one remembers.
