I know I have a very agreeable personality, and sometimes I do have a hard time standing up for myself. But my brother and sister don't need to take advantage of me, for crying out loud. Here's a perfect example of what I am talking about:
Yes, believe it or not, I am UNDERNEATH my brother Diego. As in, I was deeply sleeping and he just came over and parked himself right on top of me. Oh no, Diego, never mind the fact you are HALF my body weight. Somehow, I will manage to breathe.
