As usual, we set out a plate of cookies and a glass of milk for Santa. Once the kids go to bed and after we've set all the gifts out, Michelle and I (or just I) eat the cookies, drink the milk, and maybe leave a note. Andrew used to love this and really thought Santa had eaten the little snack.
This year, when Michael came out Christmas morning, Michelle pointed out that Santa had left the cookie plate and milk glass out (instead of putting them away like we tell the kids to do), Michael got mad and said, "Oooh, I hate that guy!"
Not even Santa gets a break from Michael.
