there's a couple things I want to point out. I'm 33 years old, I AM an adult and i don't act like you and I know PLENTY of other adults who are in their early 20's who are mature and respectful.
If you want people to respect you, Don't cuss so much; steal art (if you ever did); treat others like crap just because they don't like your work or whatever and stop using "fagget" and threatening to "kick" their ass.
Please, if you are an adult - act your age, not your shoe size.
