Recognize and Respect....

So I've been gone from home for a year now, I'm 21 and in all rights I'm a self-supporting adult. Yet every time I come visit my mom, she treats me like I'm still that same kid. I feel that after all this time, she needs to cut the umbilical cord. Telling me what to do, what to watch on tv. I respect that this is her house, her rules and all that but she should also respect my choices and decisions instead of always trying to handle or control me. And she always has to be in my business, asking who I am talking to or what i am talking about. Wanting privacy doesn't mean I'm hiding something.
