I read something in I'm With Fatty that struck a deep cord within me. He talked about how he would eat things, and would hide the wrappers and other evidence of his eating under paper towels.
I remember doing this quite a bit. It started in college to hide what I had eaten from my roommates, but it especially continued when I started to nanny. I would go straight from teaching school to their house, and I would hide what I ate while I was there. This was easier for me to do since I bought most of the groceries as part of my job. The mom was on another planet, and I don't think she noticed much of anything in that regard. I guess what gets to me is the sneakiness of the behavior. On some level I realized this was not right, yet I couldn't stop it.
