When my now 30 year old dd was about 5, we were at a large mall in Atlanta and she saw a teen guy with a collar and a girl was 'walking' him. She pointed and laughed and we were caught off guard...do we fuss at dd? Because yeah, she was a kid and genuinely thought it was funny. The teens didn't laugh but I don't think it was anything other than teens trying to get attention.
But I'm not sure what to think about what you saw today. Odd for sure.
