Genetics or coincidence...you decide!

Sometimes I look at my children and realize how much like Ray or I they are. It boggles my mind. The thing that gets me the most is this:

This is Faith, she is holding her favorite snack....Bologna, cheese and oreo cookies. It's an odd combination. She loves it and she won't eat bologna without the oreos....Neither will I.

I rarely eat bologna and cheese sandwiches. I don't know if she has ever seen me eat one. If she has she was young. I haven't had one in a long time. But....when I do eat one I have to make sure we have oreo cookies first and I can't take a bite of the sandwich without taking a bite of the oreo at the same time. It's weird. Freaky if you will but I have to have it that way. She is the same way.

It makes me wonder is it genetics or coincidence? What do you think?
