This girl won't leave me alone. I had every class with her last quarter and now she's taking my classes again. She asks me dumb questions, texts me questions that the teacher already answered, but ignores some of my questions, and now she's trying to get me to drive her to class one of the days. I want to stop replying to her texts and say no to driving her but I'd feel bad. Why won't she leave me alone. How can I nicely get her to go away?
