Overheard in a Thrift Store

I'm shopping in Deseret Industries (the Mormon version of Goodwill
Industries) in Vernal, Utah, when I hear this conversation between a
man (I'd say about 55) and a very young boy (6).
"Well, how ya doing, Tommy," the older man says.
Tommy says, "OK."
The older man continues: "You not kissing any girls are ya?"
What? My shoulders square. I'm on alert for inappropriate something, I
don't know what.
Tommy doesn't say anything, But, Tommy's daddy (I'm guessing) says,
"Be polite, Tommy, and answer Mr. Clark."
"No, sir." I can hear Tommy giggling.
"Well that's good, because you know what happens to little boys who go
kissing little girls?" I lean in, ready to intervene (and I still
don't know why.)
"They lose their teeth."
I can hear Tommy really giggle now. Then he slides into one of those
really good childhood belly laughs.
Turns out Tommy just lost both his front teeth and Mr. Clark knew this
and was giving Tommy a good tease.
And me, too.
