Damn, theyre so annoying, arent they? There becomes a period of time in the family when everything they do annoys you. Its not exactly fair on them, but you just cant help feeling so frustrated that they ask you all these questions, follow you everywhere you go (especially when you had friends round) or try to be like you. Studies show that having a sibling can actually raise your blood pressure by five percent. As the eldest of five, I do wonder if thats five per child.
