It went better than expected. The guy seemed like a nice guy. My wife's girlfriend was funny making sexual innuendo remarks like when she lost playing a casino machine she looks at me and says with a wink, "I shot my wad." Another time my wife was playing a machine and she turns to me, " I like to watch" again with a wink. Now I'm home and hung over. Cardio day will have to wait for another day. The only part that was a little squirrely was her liquored up girlfriend making wise cracks that she thought were innocuous to our cab driver heading to a restaurant. I looked at his taxi license and the name was Mohamed and he had an accent. I thought this could go bad quick but he had a sense of humor.
While her statements were not out of line, the winks would imply she intended to send a different message. Shot my wad is a common thing to say when you lose all the money you'd planning on gambling with. Like to watch shouldn't mean anything other than what it says. The innuendo is leaving out what she likes to watch. I'm not a gambler, but it can be fun to watch others throw their money away or, even better, win a jackpot.
Whatever, if she was flirting with you in front of your wife and her date, that's just crass.
Too bad you're hung over. It is great that you had a good time though. Even introverts are capable of having some fun every once in a while.
