WHY?

OMG Horse I feel you. Im the type pf person who tries to see the positive in everything BUT the people around me make it so hard. One day though in bible study my youth pastor had told me that if people give you attitude or do wrongly things towards you, mind your own and God will see to it. If you try to handle business on your own then God can't help you because you didn't trust in his word, ya know? Well hope I helped.
