Be forgiving. Be understanding. But do not be a fool. Some people have gone or are going through a hell that you could never understand nor survive! Remember this always before you judge, assume, or criticize.
I will always help people because I've been there myself many times. But when I realize I'm helping for the wrong reasons, when I realize I'm being lied to and taken advantage of, I will stop. I will walk away. Especially when they see nothing wrong.
