Overheard snippet of conversation between two middle-aged colleagues, man and woman. I call them colleagues but I don't actually know who they are, just know them by sight.
She: Do you know your students' names yet?
He: All the good looking girls! (with the suggestion of: 'of course')
She: I'm luckier than you because there are so few boys. I know all their names.
What that last bit meant I am not entirely sure but I was only walking past so didn't get his reply.
Speaking of walking past I do get frustrated. I overheard a student saying 'So she called me up and said, I'm sorry but I can't be your best friend anymore because...' and I was walking past, in a stream of human traffic, so I missed the rest of it. Damn! I so much want to know.
