Sibling 911

My "siblings" are strange. All they seem to do is sit in front of the t.v. or play on the computer, all the while I'm stuck watching over them. Though, in spite of age differences, I can not say that we have nothing in common. My brother my be bit of an airhead, but we watch similar shows. My sister and I like fashion, so I suppose that counts. Actually, no, I take all that back. My brother makes "meow" noises and watches boomerang to relive the oldies-age and my sister is loud and mean. She takes things without asking, she goes into peoples stuff without permission and she has mood swings. My brother is no better, when he gets a girlfriend he blows her off the next day and breaks up with her--what a jerk ( ...Jenny...). Though, the more I see them socialize with other people, the more I believe that they have autism, but they don't! Well, what can I do. I'm stuck with them.
