I have never understood trying to be nice to people and them acting all nice to you and then turning around and stabbing you in the back. I'm not the type to tolerated two faced biased hypocritical people, my temper just won't allow it, but I will this one time because I truly think that carma does come back to haunt you, and one day this person will have to answer for all the turmoil and stress they have caused. Hopefully they will repent before God gets a hold of them.
