I came to see what the general consensus would be
I have two friends who are avid divers and they've been married for years. They do quite a few dive trips within SEA every year, and they often blast out invites to all the diver friends. So I get to tag along without being the third wheel...Thank God!
From what I see, it's a pretty sweet deal they got there, and perhaps I should ask "do you dive?" next time when I meet a guy ... or would I be seen as show off??
Not at all. My daughter talks with her prospective boyfriends about diving. Her current one is a commercial diver. They get along great.
I also think being a third in a party of divers is not a problem ever. Not for us anyway.
