This evening, I met a prof on a busy street corner. I exchanged books with him, chatted for a moment and then walked away. While we were exchanging books, Christopher (who came along) asked us, "Are you intentionally trying to look like drug dealers?" (It totally hadn't occurred to us; we were just thinking "Hey! We live close to each other, and so instead of travelling to the University to exchange books, why don't we both walk half-way? ...to a busy street corner?)
The prof was also going to give me some money for some photocopies I did, but thanks to loud-mouth Christopher, he thought better of it and said that he'll give the money to me at our meeting (at the university) on Tuesday.
(Chris still maintains, "The only reason why we weren't swarmed and busted is because no money changed hands.")
