I'm sorry about your ban :( . I will follow you down the only road you've ever known. You are not on your own >:) !
1: Your status updates. 2: What Duf said. 3: How old you look. and 4: What the "from" thing says. I'm sorry if this sounds stereotypical, but I always want to be sure, plus I'm not the best at telling differences between some things.
Lifetime:
