The old Vic.

London underground. The Victoria line - old and very over-crowded. Friendly commuters sometimes try to spark a conversation and say 'we are packed in like sardines in a tin'.. Which is of course the 'standing' joke. The seated people never say it.
From Tottenham Hale you can get off at Seven Sisters, and wait for an empty train where you can get a seat for the rest of the journey which is typically to Oxford Circus. I don't do this. Instead I stay on the over-crowded tube.
Firstly, this is because I don't trust that there WILL be another tube so I stay on one I know is running.
Secondly, I find it weirdly interesting to watch people's reactions to being so close to strangers that their personal space becomes a matchbox size area just in front of the nose. I have seen some real gems from the classic 5ft girl's nose up against a 6ft armpit guy to the shopper plonking her John Lewis bag on someone else's pushchair/baby!
