Let me tell you a cute little story that I think says a lot about free enterprise and also about raising a kid.

It also says something about the Yankees.

I skipped work the other day to catch both games of the Yankees doubleheader against the Mets in The Bronx. Between games I grabbed something to eat at a diner and noticed a kid walking around to each table selling something.

He didn’t come over to my table because I was in the back, so I couldn’t learn any more at that time. But the kid looked about 12. He seemed to be overcoming nerves each time he politely approached a table in the restaurant.

When he left the diner, I noticed through the window that he was on the street corner talking to an older kid — maybe 18. Naturally, being a native New Yorker, I thought that was suspicious.

As I was walking over to the stadium, I saw the two again on another street corner. The younger kid, it turned out, was selling Welch’s gummy Fruit Snacks. A dollar apiece.

I asked what he was raising money for, and the kid told me he wanted to buy a PS4. Me being a guy who was around when the first video game was developed and even played Pong in the window of a storefront when that game was new, I should have known that he meant the $200-plus Sony PlayStation 4.

But I didn’t.

That’s when the older guy chimed in to explain to the dummy who was asking. The older kid was selling “ICE COLD BOTTLES OF WATER!” — loudly, just like a lot of others around the outskirts of the stadium.

And, it turns out, the older guy was showing the kid how it’s done.

I don’t know anything more about either of these guys.

But I like to imagine that the younger kid’s parents told him that if he wanted a PS4, he would have to earn the money himself because they either couldn’t afford it or didn’t want to afford it. So that’s what the kid was doing.

I gave the younger kid $2 for a snack and headed home. Only later did I think it might make a good story for this column, so I wished I had asked more questions.

I looked for the kid after the game, but he wasn’t there. Let’s hope he sold out and made a few bucks toward the PS4.
