@Adam_Mangione From what I've experienced I think part of it is finding common ground. "Oh you've suffered a level 2 trauma? I've experienced level 3 so I understand what you've been through". If they act smug about it after that then it's a poor attempt at flexing.
Look I don't care if you're voting for Bernie, Warren, or any of the others. If you aren't washing yours hands after going the bathroom, ESPECIALLY during flu szn, you shouldn't be allowed on a college campus.
