After my 3rd youngest sister was born, I knew I didn't like siblings so much. There were just to many changes, and too many sacrifices that I had to make. First I had to share my toys, then I had to share my room, and even worse was that I hardly got any attention from my parents.
My parent's just keep telling me when I was older I would understand, but I didn't like that answer. It wasn't a fair answer, and it really just seemed like their excuse for not spending time with me. It was the handy excuse for every crappy thing that happened because of my brother and sisters.
