The other day on the tram around lunchtime, there was a group of kids, probably about 8 years old. That’s not unusual here. Kids walk to kindergarten alone, they ride the trams by themselves (although I usually see them in pairs or groups).
This group of kids were entertaining themselves with a singing and hand game. It looked suspiciously to me like “Rock, Paper, Scissors”, and I listened closely to the words. Yes. They were singing “Schneider, Stein, Papier” as they shook their fist before making their choice.
I really wanted to take a video or a photo, but that would have been out-of-bounds, so I just imprinted it into my memory.
