Kitty, I don't know a sibling that hasn't gotten into it with one of their brothers or sister's. My brother and I almost came to blows over a tv show. He threatened to punch me and me being the youngest and a smart ass told him to go ahead, I would tell our mom when she got home. He knew the channel war was over and he was not the winner. Aside from all our differences my sister, brother, and I are extremely tight and have each other's backs.
