Well, thanks to a signal failure last night, it took me 2 hours to get home (normally journey 40 minutes) via the useless South-Eastern trains - roll on the London Olympics when the real fun and games begin... If it was chaotic last night, we haven't seen anything yet!
Anyway, as for the weather, I am off to work in an air conditioned office later this afternoon, so it can get as humid and hot as it likes!
Edit - well, that is until it gives SE trains another excuse to cause chaos. Usually it's buckling train tracks in the summer...
