It happens all the time. I just don't get it. I just can't imagine me doing such things. It's sad there are many people in the world who are capable for doing such thing..
Don't treat people in a way, you don't want them 2 do it with you..
I most of the time never forgive them, but I just move on with my life, even if it's difficult, you have to make sure negativity stays out of your life
