SD is 11, and most of the time I can not stand her. As soon as she wakes up in the mornings I get in a bad mood! She talks like she knows everything, I swear one day I heard her giving marriage advice I mean you have to be kidding! When I try to talk to anyone about the way I feel about her I get the same response across the board.  "She's just being a kid" or "That's how kids are ". I get along with kids, most all kids. But this one I despise. She is always right up mine and her mother's ass!
