Sorry to carry on the milk debate, but I always put it in after the water and I'm told I make a fantastic cup of tea ;D even though I don't like it myself.
If you go to the cinema to see a movie with some friends, SHUT THE HELL UP!! The most annoying thing is when a bunch of morons sit behind you and talk all the way through. Or if a bunch of chavs come in and start kicking the seats and throwing popcorn etc. Actually... just wait to see the film on dvd and don't ruin my cinema experience.
