On Trust

We have been talking a lot lately about trust and how people who trust each other are close and how as a family I want us to be close, that being one of the reasons I didn't want them to go to school. We also talked about how when people lie to each other and trust is broken that sometimes we lose that closeness. Anyway as we were discussing this Sara said that she thought that all parents lie to their children about things they do not want them to know. I had to thing and as I thought I really couldn't think of anything that I have lied to them about. Except one....... the Big guy with the white beard. I come from a traditional family and that tradition carried on with my children. Except now I am full of guilt! Do I tell them he is not real?? I remember finding out and being devastated and I truly believe my oldest still believes. SO now I am torn do I tell just her or all and will she think it was a lie. which essentially it is.
