I was in the Navy, assigned to a barracks in Italy. There was a female Sailor who worked in the barracks. Miss Super Proper, obeyed all the rules and regulations to a tee. I found it my mission to violate every barracks rule just to annoy her... she managed to get me reassigned to the smallest possible room for my paygrade. We made life utterly miserable for each other.
One night I was headed out to a popular club in town and my female friend asked if she could bring a friend along. SURE!
It was HER, of course. My arch-nemesis, and I'm driving her around Italy! GRRRR!
Anyway, the hours progressed and I thought I'd ask her, since she knows everyone in the barracks, who she thought would be worthy of a road trip with me to the East Coast on a whim. She grabbed her drink, ready to throw it in my face, and said, "Yeah. ME."
"Okay." She was stunned that I didn't just laugh her away (and wear her drink home).
So the trip was coordinated, we got the same days off scheduled, and hit the road east. As we talked, I found things we had in common and things we didn't. She had been treated horribly most of her life. I was a lonely introvert. After a miraculous rescue off the side of a mountain, spite turned to acceptance, which turned to like, which turned into love. It's a novel waiting to written, I tell you.
That was 1987. The Navy then pulled us in two different directions: she transferred to Greece, I came back to a U.S. based ship. But Fate had another ace to play: in 1990, she transferred back to a base 15 miles from me! I supposed it was meant to be, and one night I proposed to her.
We just celebrated our 25th Anniversary together.
