I have no idea if this is an Aspie thing, or a normal thing.

My dad cooks all the time. Sometimes, he cooks something new that is very awesome and very perfect. Then, the next time he cooks it, I get all excited and stuff. I get a bowl, sit down and... he changed it, and I HATE change. It's no longer the awesome thing he made two weeks ago. It's this weird, spicy thing that tastes completly different. I pretend to like it, but he can normally tell if I'm lying and gets in a bad mood. My mom then calls me an Anorexic because I refuse to eat anything (even though I was eating it), we get in a yelling match, and I go upstairs to the safety of my bed and the Internet.

I really hate it. Any tips?
