A close relative of mine has a friend who has a sibling about my age I would see her friend with her sister when I was over or around the house we never spoke to each other but I ve seen her more than once. Now she s in my class and I know who she knows who I am. Since the beginning of class I ve caught her looking at me and other people have told me she was looking at me. It makes me really uncomfortable and I just want to know why she s looking at me. Am I overreacting I just think it s weird we don t talk and today she didn t want to walk by me I don t know what that s about plz help
