Reminds me of years ago I was on a military base in a foreign land. The local troops were staging a war game of being attacked from foreign countries. I had to wait in a court yard so I decided to call my father because it was father’s day. As I was talking to him some special operators let off machine gun fire. My dad said, “what the hell is that? Is that uzzis?” Uh, that’s machine gun fire dad... They’re having a drill here. Maybe I should let you go dad. Heh, heh. He probably still thinks I was somewhere where I shouldn’t have been. It was a fun day though.
You need to read the story, “I took Grandma to Nam” by Sonny Hoffman. You’ll find it with online search.
