You liked being called out of your room ten times a day for some bullshit you've already explained a million times? Being asked to type something because you type faster?
Thief is the perfect word. Instead of using their own brains they stole mine. I don't know how someone does this and isn't ashamed of themselves. I'm so glad I don't have to live the life of a helper monkey for the terminally lazy anymore. Magically they managed to survive on their own once I moved out. Go figure.
