Apparently, I know things all the time. Not that I necessarily do, but people seem to get that impression. Classmates keep asking me how I solved question so-and-so on whichever exercise sheet or where the lecture was moved to next Wednesday (never mind that I wasn’t present when the lecturer announced the change of venue). This is of course rather flattering (in particular the bit where they ask me to help them with coursework).
It was a bit more surprising when I was sitting with my back to a pillar at the train station in Metz in July, drinking milk out of the bottle, sweaty and feeling more or less brain dead, and a girl walked up to me and asked me about the next train to Sarreguemines.
