Pardon my bad if I intrude on your parade but she's only twelve.... Of course its going to be childish, we don't write to entertain you. We write to entertain ourselves, we just let you random people read. We don't want to grow up, mature and all that. We just want to be young until they draw the line and we have to be mature.
Just to give you a quick summary we don't care about our grammar, we don't care if it's childish, and we don't care about you. You must have a childish mind to read our work. So I guess what I'm saying is that your growing up to fast or your just a grown up ruining a child's dream. Thanks for understanding love, Cheers :3
