you tell them everything. you have nothing to hide. you always just WANT them to know everything and you do anything to make them happy. its not a game of 'i dont feel like talking about it' or 'i didnt feel like doing it, just because you did it doesnt mean i have to back' you just want to. thats how you know its a best friend. when you WANT to be better to them than they are to you.
Julies a bad best friend, she doesnt even tell me whats wrong.
