People have a good reason to be afraid of tear gas, considering it's a banned agent of war under the 1993 Chemical Weapons Convention. Here's the catch - there's a clause in the treaty that includes an exception for domestic use. Yes, it's illegal for the U.S. military to use tear gas against ISIS, but cool to use against American citizens.
You realize, as time goes on, there is a certain expectation now in 2018 where fans want to see cool, exciting, hard-hitting sports entertainment or hard-hitting pro wrestling, and there are ways to give them that without necessarily putting yourself in the hospital that night or not being able to move the next morning.
I think making friends is not being afraid to look stupid, because everyone wants a friend who is willing to be stupid and fun. If you try and be too cool, it only works in high school. After that, being uncool is a very cool thing to do. So just have fun, and don't worry what other people think of you and people will want to be your friends.
