Now I can give instructions on how to crash the party of a 20-year-old guy in Toronto. You need to have a great camera. You need to have some insider friends among those who are celebrating. Preferably, this insider will have forgotten the keys to his place, and his parents happen to be your friends. Of course, you need to be coming back from a great party yourself, in order to look tired, but not too tired; well-dressed, but moderately so. With a little glint in your eye, hungry for adventure.
