I just heard about this. All groups of kendama players must adopt this immediately!

so obvious when stated like that, one wonders why we don't do that by default.
Right on! On a fundamental level this is a simple heuristic for good manners & being welcoming to new people. I imagine there's some interesting psychology at play when people open or close groups consciously or not. But great rule of thumb especially for a group of dama player. . . I must admit the first thing that speaks to mind when I saw the title was, "what?! Eat ghosts?!" 😂
