You know there is only ONE answer to the question, "Were you checking her out?"
"Checking WHO out?"
Any other answer and you may as well start walking home. And that's when the fight started...
There's much less to "observe" since I moved from the city to the 'burbs. That lakefront trail...oh boy. Especially down by North Ave. Beach.
Honestly the funniest stuff was when my wife and I were dating and we'd be downtown together. I'd watch the dudes we were about to pass on the sidewalk so that I could witness this sequence:
Dude checks her out
Dude looks at me
Dude figures out she's with me
Dude realizes I'm looking at him
Dude realizes I saw him check her out
Dude panics for a split second
Dude tries to act natural like nothing happened and he wouldn't know what I was talking about if I said anything.
Boys I'm here to tell you, we think we're slick and we're NOT. We're obvious, and it's funny if you spend your time watching for it.
She told me a story one day of some guy who turned around to check her out and walked into a lightpole, then his buddies all laughed at him and yelled it out for everyone to hear.
My wife and I don't really do the jealousy thing. I can't trust somebody who wants to pretend I'm the only man who exists or the only one she thinks is good-looking. No I'm not, don't be in denial like that. Make an active choice to admit I ain't the only dude in the world, I'm just the only one you want to be be with.
I don't waste my energy being jealous. If other guys aren't looking, what does that say about my taste? Some guy crosses the line and doesn't know when to knock it off, we can sort that out. But otherwise I take it as a compliment.
