My guilty pleasures...
Wearing headphones not plugged in to anything and listening to people's conversations on the bus/train.

Humming really tunelessly in a crowded room and seeing how long it takes before someone asks me to stop.

Standing really close to people I don't know to make them feel uncomfortable. They often move away with a slightly puzzled look on their face.

Sitting on the bus and holding loud conversations arranging terrorist acts on a switched off mobile. A favourite is to talk about blowing up the bus I'm on, pulling a worried face and saying "What, that soon?", immediately pressing the bell and getting off at the next stop. Even better is describing people on the bus to my imaginary contact on the phone, always calling them the 'target'.

Looking people through their windows - not doing anything dodgy, just the housework or watching TV.

Tapping strangers on the shoulder and walking off.

Pretending to follow people while furtively looking around.

Um. I think I've already given away too much about my personality. I make no apologies for length or technique.
