No, you may not have peanut butter M&Ms and chocolate milk for breakfast. I don't care if it's finals. A diet like that will make you balloon into a million pounds. People will look at you and go, "there goes that FAT girl". For Halloween you could put a sheet over your head and go as one of the Andes mountains. NOT ALLOWED to happen!
Now, either go make a healthy breakfast, or get back to working on your paper.
