I really want to go dye eggs and eat watermelon with my mom and my sister and her 3 kids but she brought her annoying ass boyfriend. I was really hoping she would leave him since he's been being a dick to her for no reason but appearantly they've "fixed" things but I know it won't last long. grrrr. it's the perfect opportunity for some pictures. but I really can't stand him and don't want to end up fighting with my sister again
