He's my nephew but love the kid like a son definitely
I hear you on that element of getting to share activities esp video games with the kids, you get some of the childhood vibes coming back and the nostalgia is great tbh. Letting them score in madden to gain confidence initially, two weeks later they are actually beating you (I was the same way as a kid, leave me that game for a week and I will learn it in and out)
The world could be burning down around you and you wouldn't flinch...meh, well this is now our new world! lol
