Grandma has Lost Her Freakin Mind!!!?

Okay, I'm 14 years old, i usually don't get in trouble, im homeschooled, and of course, its saturday, so i don't hafta do schoolwork today. I live with my grandparents, i weigh somewhere around 115 lbs. today, i had a PB&J sandwhich, and a piece of cake for lunch. Then i was making chocolate milk, and my gma walked into the kitchen and said that i couldn't have chocolate milk and chocolate cake all in one setting, and that i was "out of control" and that i have many "problems to be taken care of" shes like, 47 or somethin, and could anyone tell me why she ****** flipped out? thanks
