Can anyone say hypocrite?

Why is it the little things that I nag Gracie about are usually things I did as a child? She has a new Princess cereal that is a mix of the Captain Crunch Berries (heart shaped, of course) and Lucky Charm marshmallows. For some reason it really bothers me that she picks out the marshmallows and leaves a full bowl of "nutrition" (at least it is made from whole grains). She absolutely refuses to eat the other pieces. I don't know why this surprises me. . .when no one is looking, I still dig out the marshmallows, too!
