Welcome to Bellum Letale. Don't suggest fire in the building, even if it's a warning against it - someone might take it seriously. The people here are not crazy, despite popular belief.
It's recommended you don't leave your apartment unless armed with your room key, cell phone, flash light, and your choice of self-defense tool. Mace is popular. Be aware of who you're around and with and the people wandering the halls at night are there to protect the residents.
