Erik, I can agree that when a young player is taught to behave a specific way by the authorities, he (or she) isn't being rude intentionally. Outside of those types of competition rules, what do you teach your daughter to do? Do you draw a line between "following competition-specific procedures" and generally appropriate behavior?
I guess my motivation for asking, I'm happy to play with anyone at any time, including young players. I think there's a lot to be learned, on both sides, by playing outside of your own demographic, but I wouldn't want to overstep by giving advice with the best of intentions.
Some very chatty people recently and hate overhearing people talking swing thoughts, so put on earbuds the other day. Don't do this often and the muted effect of not hearing your strike in full is weird. Is this something you get used to? I'm using something similar to Apple's AirPods.
