This girl at my school is following me everywhere (even waits for me outside of the bathroom) then she acts like she has a crush on me (for instance if I look away she looks at me with a weird expression on her face (her mouth smiling and... Well I can't tell you that) anyway she is pretty and nice but the thing is she is a bully and she is only nice to me. So please just help me out with this (I don't really want to disappoint her)
