I talk to strangers, it depends on the moment.
But I make a point of saying things to kids at Folk Festivals. Especially dances. Usually kiddy type jokes, but it helps to include them in the genre rather than just be dragged along by parents. The Folk World needs the youngsters to feed the other end of the conveyor belt that is "aging". Some of them are so talented it is scary, but they were probably going to be musicians anyway, luckily they are Folkies.
Kiddies do say things to me, at Festivals I am a bit noticeable.
The other day some kids at a bus stop were all intent on their phones, then two asked me if I was, like them, on "Team Valor" (seems to be characterised by red). They were playing Pokemon. Just as a joke I said "No, Team Ducati" before they could suggest Liverpool or Man U.
Educated them on the diversity of life. A bit.
