My wife got certified when she was around 17, but always preferred just beach combing and snorkling. She probably wore a tank 4-5 times after initial certification and just drifted away from it. She got recertified 7-8 years later when we began dating. She dove with me a few times, said she had a nice time, but really does not enjoy the encumbered feeling of a wetsuit, BC, weight, reg in her mouth, dive boat ladders, and some other things that thrill me.
She is very supportive of my diving habit though.
Golf, Deer Hunting, Scuba, whatever. She thinks that guys should be allowed to do what they want to as long as nobody gets hurt in the process.
We just had our 20th anniversary, so it seems to be working for us.
I dive with two David's, 1 Dave, 1 Davie, and one guy who pronounces his name as "Day-Veed".
Chug
Dives with five guys named "David", sometimes at the same time.
