Why do we do the things we do?

I don't know. I just know that I always inevitably end up hurting the people I love most because of the things that I do.

Maybe we're scared that if we do what we are really supposed to do, or what we really want to do, we won't get the reaction or response that we want so we end up doing thoughtless things that hurt the people we love so that when they react negatively we are at least assured that our real emotions are still securely masked.
