How Not To Kill Your Friends: Step one: Breathe. Take a deep breath and hold in that negative energy. Step Two: Breathe again. Think of a happy place, a place where people's brains are not getting smashed to the curb by your baseball bat. Step Three: Breathe once more. If that doesn't work, write their name down on your list and then kill them later on in the week once you've got some spare killing time.
