My recently passed Grandfather (92 years old!) volunteered for diesel electric sub duty in WWII. I was always proud of this as I knew it took some balls to do such a thing.
What I didn’t know was that it was an utter act of insanity on his part.
One summer, while I visiting, he was working on an aeration fountain for the decorative pond in the backyard. I commented that it was a pity it wasn’t deeper and bigger, that way we could swim in it. (Summers were very hot where they lived.)
He replied that he couldn’t swim. (pause)
To which I replied “What do you mean you can’t swim?”
Grandpa “I sink like a rock. Always have.”
Me “Then how did you get in the Navy?”
Grandpa “I could hold my breath for 2 minutes.”
At this point it took me a few seconds to formulate a response.
Me “TWO MINUTES??? FAT LOT OF GOOD THAT’D DO YOU AT THE BOTTOM OF THE OCEAN IN A LEAKY TIN CAN!!!” At which point I stormed off to the house. When my grandmother asked what I was obviously upset about, I told her “he’s crazy!” and said nothing more about it.
We never spoke of it again. I still admired the man for his service (he served from WWII until the start of the Vietnam war, and retired a Lt. Commander) but it only demonstrated that for all his bravery and intelligence, he was essentially just as bat shit crazy as everyone else in the family.
