At Hamilton on Saturday, there was a young boy, maybe 8 or 9, wearing a Young, Scrappy, and Hungry T-shirt two rows in front of us, and we were even wondering if he going to get much out of this performance?! But then in act two, when (spoiler alert) Burr shoots Hamilton, this kid loses it, and starts wailing like he just lost a loved one. He was inconsolable, and his father or whomever was next to him had to put his arm around him, while the kid buried his head into their shoulder and continue sobbing. After the show, we all decided he really was following everything and invested.
But, he is not the bad theater behavior. After he is wailing, which was admittedly loud and a bit distracting, the lady in front of me tapped someone else in their party on the shoulder and said, "You should get him out of here, he's annoying everyone..."
A bit of an outlier in this thread, but figured it was worth sharing.
