krizSLPT: If you feel nervous in social situations, try open carry. Now everyone else is more nervous than you are.
One of my DnD members would come to my place open carrying. I asked him not to bring it with him in the future. He now Carrie’s a 12”+ knife with him to the table -.-
Maybe you should figure out a safe place for him to stash his weapon while in your home so you can relax when emotions flare during the game, and he can feel safe on the street.
jeffwTo add to this, I’d do a quick google search for free gun locks in your area. Some places give them away
