Maybe its because of all the negativity around them that makes these persons see differently. Have you ever heard voices about things around you but didn't know what to do about it? This is why their reactions are from experiences that aren't according to some appreciated. Oh... that T's me off!
But I deal with it. You know what I've learnt? Just take one day at a time and don't worry because tomorrow will take care of itself. And learn to forgive even when your heart is bruised and battered. I would hate someone to come up to me when one of my parents have passed away and mention the fact that I didn't do anything for them. Time will heal all wounds.
