When I was little, my grandma(maybe grandpa too) told me that if I didn't eat I'd get smaller and smaller till I could fit through the crack under the door. She (they) told this to my cousins too. When I was about 6, I believed this was true and I really wanted to grow. So that upset me. Till I grew up enough to realize it wasn't true. I've skipped meals before and I'm the size I'm supposed to be. I'm still here.
