Cos they are really good!
Also, I have to share a conversation that I overheard on the bus back from UBC the other day.
Boy: "So what are you going to do when you finish this degree?
Girl: "I'm applying to dentistry."
Boy: "Are you seriously into being a dentist?"
Girl: "Well, I really like doing all the moulds and impressions and stuff."
Short pause.Boy: "Why don't you just get into pottery then?"
I thought he had a point.
