My dad works at a huge restaurant, hes a cheif. A couple months ago one of my dad's workers had to fire one of his cooks. This man is mentally unstable. He came to the club three days ago, walked up to one of the employees and said, "If I had a gun I would shoot *insert name of old employer here*", so he called the cops. They came, they asked questions, they went out to find the man. Apparently he hasn't been to his house..he has been calling people who work at the club telling them not to get involed. So last night I took a huge butchers knife, hid it under my bed, and just staired at the seiling. Should I be this frightened?
