Brandish a weapon in an argument? pfffft.
In 1965, my dad got into an argument with our landlord. The landlord claimed I'd started a fire in his garage, but I was upstairs in the flat with my mom & dad. The landlord and my dad had a fist fight, the cops were called, and the landlord went to the pokey.
We're going back in time, everyone has a gun now, be careful out there. Never argue, walk away.
