First advice-Why should girls not have crushes?

Ok so welcome to my blog and what girls are mostly looking forward to is....guys always.Ok so this is my question from a friend.There are tons of reasons why you shouldn't really have a crush.First of all im just saying it is just a little to much.Guys dont understand girl's signs.No matter what they have no idea you are trying to tell him you like him.Also it can ruin your freindship.You don't want that.Also it starts fights..... Obviously just be your self and all but don't ruin your childhood!!!!!!!!!!!!!!!Guys out there i'll tell u i used to like guys but not anymore.I started thinking about my childhood and i dont wanna say hey i remember i wanted to have a boyfriend when i was a kid.No....But think about.
