Is this wrong of them? Or is it just me?

Okay, first of all, a spanking is one thing but beating a child for no apparent reason is wrong. They are hurting you and I know you love them but you might have to let go of them for a few years. It'll be best for you and your sister. People like this manipulate others into thinking that your wrong when really, you're right. They feed off of things like that. I'm glad that someone is looking after you enough to send in that letter. That means someone cares. They are wrong. It's not you. Believe me. I hope things get better.
