At our house, I do the grocery shopping and the cooking most of the time. So when I shop I buy tend to buy us a few snacks, treats, and yummy entrees. Because I also put them away I can't be held responsible for not telling Fred everything that I purchased and it's exact location in the house.
I will admit that I use this to my advantage because
Fred eats us out of house and home. If I want something I have to eat it fast whether I'm hungry or not or…I put it on a shelf he can't see. Once again…it's not my fault he doesn't look around.

Lately I've been buying fruit snacks. I put them on the shelf in the pantry that also has crackers and other items of the same snacky nature. I had two boxes. I ate an entire box by myself over the course of a month and when I noticed the second box had gone untouched I knew he had no idea they were there. Nothing of that nature would last more than a day if he knew it was there.
A couple nights later, he was looking for something in the pantry so I told him it was on one of the bottom shelves. As soon as I uttered the words, I gasped. My secret was out.
Moments later I heard a "What the! How come you didn't tell me we had treats"
In my head "because I'm not stupid"
out loud "oh…you didn't know they were there?" within a day that entire box was gone as expected.
This time there was a box of Fruit by the foot that I have been successfully
NOT HIDING on the bottom shelf of the pantry for over a week and a half.

Last night, I got home from work and Fred was at class. I went up stairs and in our room was this:

A fruit by the foot wrapper. Crap. I've been discovered.
It's not my fault he doesn't look through the cupboards.
