It's a toss up
My sister, but she lives 400 miles away and has to take care of a special needs child. We talk about everything but she's far too busy to talk to me much...
A classmate at school, but I don't see her being my bestie after school. She has kids to take care of and she's 15 years older than me. We never hang out or really talk outside of school. but at school we're inseperable.
Another friend at school but she's annoying with projecting her absolutely poor self esteem.. and she flirts with me ALL THE TIME which.. um I don't swing that way. Plus when it comes time to go somewhere, she's like "Where should we go??" like I'm a guy and I have to pick... even though she knows I'm trans...
Bleh, there's no gay guys in this town and a ton of ->-bleeped-<- hags, so I guess until I transition, girls will want me to be their gay friend

I guess that's why I choose the middle girl as my bestie around here.. she actually treats me like a girl and almost thinks of me as one. I've told her everything and when I get emotional or whatever, her response is basically "welcome to being a girl" ... and she NEVER gives me that ->-bleeped-<- hag feel... you know, too clingy and giggly and insistant about talking about her freaking clothes or boy problems.. and only about those things. (Not that I mind, but some girls USE gays for that)
