Some people walk around just waiting for someone to say Merry, Happy, whatever so they can lamblast them. The world is full of creeps. I say Merry Christmas unless I know the person does not celebrate Christmas. I don't care if anyone does or doesn't, why do they think anyone would want to care what they celebrate anyway. I had one woman tell me she did not appreciate me saying Merry Christmas since she was not a Christian. I said okay then Pooh on You. Is that nicer then Merry Christmas to you? I have had people say Happy Kwanza or Happy Hanukkah to me I say Thank You like any decent person would.
