I can't stand a person who is nosy.

I have a classmate that is so nosy. She looks at my grades, she wants to know how I got my grade, because she said," I don't participate all the time". What business is that of hers. She picks up my paper off my desk and look at it. If I am talking to my friend, she buts in and want to know what we are talking about. I am really getting irritated, annoyed, and frustrated with her. She gets on my last nerve. If I have a snack to eat, she wants some. She is also greedy. Could you image a person that is irritating, annoying, greedy and nosy. All this in one individual. Help me pleased!Credit: Yahoo.com
