Stop in for a cup of coffee
I knew 2 WWII submariners that were friends of my grandfather. They were both little guys like him and crazier than batshit. One of them had taken a bullet in the leg from a Jap Zero that strafed them when he was on deck. He also was on the boat that sat on the bottom of Tokyo bay for 14 hours taking 137 depth charges before they surfaced and torpedoed a bunch of enemy ships before getting the hell out of there.
We used to call him “Pappy”.
