She's just a girl, who says that I am the one... but the kid is not my son

I went to get my hair cut today. I went to pay and the beautician (handsomtician... is she still a beautician if she's cutting my hair?) said, "Are you paying for him, too?"

"He" was a guy in his late teens or early twenties, sitting in the waiting area.

"No," I said.

"Oh," she said. "Is he with that guy getting his hair cut right now?"

The guy getting his haircut was also in his early twenties. I had never seen him before.

"I have no idea," I said. "I don't know those guys."

"Oh," she said. "Sorry. I just heard him say his Dad was paying for him."

Luckily I hadn't given her a tip yet.
