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.
It’s not that I’m really that nervous about it. I just don’t see the need or justification. We’re literally doing one of the lowest-stakes activities one can do. It’s like those assholes the open-carry assault rifles on public street just to exercise the right. I hardly think he’ll do anything with it, but why have it to begin with?
