"Hi. Uhm. I don't know that we've ever met so I really don't think that you coming to my room would be such a good idea even if your phone is making a noise. Or do I know you? Your number wasn't familiar and I don't recognize your voice. Are we in class together? And why would I stab anything? With what? Well, I guess if I had to, I could use my pen to stab someone. But still, I think if you really want to meet me you should ask properly."
