I have a female friend who dress up and acting like a boy behavior. she like electronic and game. computer stuff.
she never wear make up, or a skirts and purse . sometimes, I notice her not even wear a bra on because she have very flat chest and she have a very short hair with a single ear rings on left side. what is wrong with her do you think ?

thats just her style? isn't it weird to ask strangers for advice? you're supposed to be the friend.
