Input: Or this one, since we're fantasizing: 1. Today, we learned about covalent bonds in the chem lab. 2. We heard a car horn! The school is on lockdown and there may be an earthquake at ANY MOMENT. Someone said something about an astroid that might hit us some day! Also, someone saw a muslim guy who looked suspicious! We're going to hide under our desks until Pete Kelly saves us with his magic laws!
Only a coward needs a gun to feel safe in a free society. Yeah, you might get punched in the nose or struck by lightning. Or, shot by some moron who doesn't like the way you drive. My point is, there is always some risk of disaster or violence. In my privileged, reasonably safe little part of the universe (USA), that risk is so small that I'm not going to waste my time worrying about it; seriously, I have better things to do.
Output:
Yes
