who would?

Maybe someone wants to do that if he/she doesn't have someone that close to him/her.
It is hard to find a true friend who doesn't care about anything, just want to make a good friend. We can share the secret with him/her, but we need to make sure that he can keep that secret from the other people. He/she will be our best friend in the sad and happy moment, and he/she will always be on our side whenever we needed him/her.
