Re: Wrong girl for brother
^ I'm sorry, but this is laughable. Your brother has a girlfriend who "lured" him astray, but you have a boyfriend who "changed" for you. Let me guess - your relationship is innocent, but your brother's is not? Hearing girls who have boyfriends/girlfriends complaining that someone led their brother astray is just a wee bit hypocritical.
Then again, tell your parents about your brother - at least it may serve to distract them ;)
