do you trust me?

I beileve there are only very few people you can trust with most things but, but maybe not entirely everything. For example, i tell my younger sister Lizzy everything, shes 13 and she knows most of all of my secrets. Shes not only my sister but my bestfriend. I also tell my mom everything even if she doesnt wanna hear it because shes also my bestfriend. Another person i trust to tell things to is my bestfriend. but besides thoes people i feel as though whatever you tell someone their always going to tell atleast one other person. Everyone says "i promise i wont tell anyone" but what it really means is anyone besides my bestfriend. if you have a bestfriend your bound to tell them everything and anything someone else tells you.
