I agree talk with security if your building is in a good area (which it probably is) they have cameras whether you see them or not

 

set your apartment building on fire then leave Calgary for several months. tell no one where you go.

 

I agree with the punk kid idea. If it's not, I doubt someone is going to go from a flat tire to broken glass and smashed in body panels in one step. If you know that no one has a reason you hate you as a person, then I wouldn't loose sleep over it. Don't let a miserable bored dumbass affect you like that. Or you can just shoot him. I dont care I also like the BB gun thing. It's comical to visualize.
