Pog mo thoin! I only remember the rude stuff. Literally read a bumper sticker like one time and it never left after over 20 years.
I like some of the other suggestions better than this but if you’ve already tried communicating about it and other things haven’t worked, I wonder if for some cases you could convince him to take a video or a picture. Like, if it’s a cool thing he wants you to see instead of interrupting you record it and share it when you’re available instead of right now, interrupting you. Again, I think the other proposals are better but I wonder… if you’re right about the motivation at least sometimes being just wanting to share something it might be worth attempting.
Shouldn’t athletes expecting to medal just want to skip the competition and go straight to the podium? I mean, that’s the reward, right? It is pretty easy to come up with many other analogs where there is a reward/goal that would feel hollow without whatever experience precedes it.
