Okay....
I have a classmate who always seems to be freeloading off of me. For a while I thought she was my friend, but now I just feel like she uses me. She uses me for rides to places, my washing machine and dryer and now recently got upset with me because I didn't want to sit on the phone and give her the answers to our homework, let alone talk on the phone when it was late because I just wanted to relax. Now she's giving me the silent treatment, but I know that'll end to next time she wants something from me. Any advice?
