I have to have a fake "happy" dinner at Soup Plantation tomorrow. Blech!?

I know I'm not perfect in the least, but MY FAMILY...Let me tell u!! Actually, there's not enough time in the day or room on this thing to go into detail. I guess what I'm asking ..is I guess, should I just pretend everythings great and be happy n stuff for my grandma? There is A LOT OF HOSTILITY in my family, and my grandma just says "say your prayers and ask God." yea, ok. Anyways..Just pretend? Thanx..I feel sick..blech!
