Might just be my upbringing but I think 15 year-olds still need to learn that not everything can be perfect and a bunch of fun.
Uh, I'm 15?
Icy, your sister is probably in a stage where she believes that she ought to be the center of attention and cannot bear to do anything boring. Best thing to do, is to convince your parents to ignore her pleas when you schedule stuff like your party, and then everything should go along better. Try that and see what happens.
thanks but when she wants something she never gives up ill have to try to get them to agree with me to stop lissoning to her.
zombie just wondering do u have any younger sister that do the same thing?
Try that, and if that doesn't work, you can make your plans in secret. They can't complain about stuff they don't know anything of.
