i agree with pegasus. it all depends. like at work, there are people i have to deal with all the time that i dont like, but i am nice to them because it is part of my job, so i am civil to them when i am around them. but if i were to go out of my way and befriend them and suck up to them, take them into my confidence and say things opposite of my "trash talk", well then i would then be being two faced.
