Things I have started to say:
"air con" (in lieu of A/C)
"holiday" (instead of vacation)
Things I've been thisclose to saying:
"bloody" (as in "really" or "very")
With only 4 days before I'm back in NYC, I feel the need to put this out there...because chances are I'm going to let one of these slip and you're going to give me hell for it.
