Yeah, Andy told him to do a drill and then started talking to his father so Nate continued doing the drill because Andy didn't say stop. Loved that Sid said he noticed this and felt bad for the kid.... before Nate said "Yeah, I was trying to impress you."
What I love about their relationship is that while Nate obviously adores and looks up to Sid, Sid seems to always have treated Nate as an equal. Sid was impressed by Nate's work ethic before he even made the NHL, as shown in this story.
Theirs is a relationship based on mutual respect. It's not just a mentor-student thing. Sid is getting a lot from the relationship as well. Their relationship seems more "Brian's Song" than "Slap Shot". Whatever it is, it's been going for a long, long, time and has finally culminated in two massive giants of the game getting to play together for the first and maybe only time as dominate players of the game. And even now, Sid's not what he once was, even though he's still better than like 85%+ of the league.
It's just so cool to actually see these two together. I know Sid will never leave the Penguins, but damn...
