her "hat"??

Now this behavior I just don't get. She baffles me. She HAS to wear this Gladware container on her head as much as possible. She just has to. She shoves in on her head (it fits rather snugly) and goes about her day. It will leave a red mark across her forehead because of how tight it is but she doesn't seem to mind a bit. Sometimes it even fogs up from her head sweating! Is she crazy? Now, she has other hats which she will not wear. So this is not a hat fetish. This is a square, plastic Gladware fetish. She even had to wear it in the car when we went running errands today. No, I didn't let her wear it into the stores. She's the crazy one not me! Here are some pictures of her wearing it allllll day.
