We had a guest provide this story, I have to assume that perhaps English is not his native language. You guys will have to take the story as it was written, I can't offer any clarity on the event he saw. Hopefully he will see the post and help explain it a bit more.
One afternoon, I am merely sitting on a bench waiting for the ride to show up. Over one hundred feet away there is a kid, a teen, who’s making noise and gets this attend. He has a buddy to whom he says 'Sometimes they will give you something for your attention', to put it mild wise. He stares this way and has a nice crotch showing. His buddy goes away as no react comes from the bench. The other makes more noises, no hellos, just noises. He gets more eye attention. His mom shows up with the car and groceries and he helps attending. He looks much over the way to his target more than a few times. Bench man still awaits his ride and dares not reply nor respond.
What can one do with such an offering, anyway? No thing. He climbs into the VW and off he goes with a last look before he gets in. What does he think he might get for his offering? Uh, what offering? One hundred feet away he notices a target. No not accurate in one sense. Bench man must go away, no matter, if and when. What does the boy see to excite him so? Rubbing his crotch to get this attendee for sure ! But What does he see to get him to be aware ? Never see him until his noises. [Ride comes soon after and target is off elsewhere.] Can not figure.
