you asked are you selfish, no you are not but this is all a bit childish and silly. She's hardly taking advantage she is 13yrs old!! I dont see the problem. you Obviously wanted a different answer to the one I gave hence why you have just agreed with saying something, I think you were going to already. I am not being nasty just telling the truth and don�t see how you can tell a 13yr old that she cant borrow your straighteners anymore. When you think of all the problems other people have to face illnesses, losses etc yes this does seem very trivial to me. Thats my opinion which you asked for you dont need to snap, you seem to take things too much to heart. x
