I'm surprised you can build anything and do anything in it, really.  I think that's what surprised me.  But also I think it’s a bit weird, like everyone is actually a person as well.  Like I avoid talking to people because I always forget they're actually really people.  I just think it’s a bit weird.  I don’t know why.  I think I'm always scared I'm going to get into a really bad conversation and then I feel, even though I know I can get away, I feel I'm being rude, just walking away.  I feel like, as if you were talking to somebody, you wouldn’t just walk away, well, I'd try not to walk away from them and be rude.
