Nirvana/Heartwarming

Kurt stopping in the middle of a song to confront a man who was taking advantage of the concert to grope a nearby woman. "Coppin' a feel, eh buddy!?"
It's incredibly sad in hindsight to see Kurt showing off his daughter. He had his issues, but he loved his family more than anything else.
Kurt asking the fans to sing "Happy Birthday" to Courtney during a concert. Love her or hate her, it was a sweet thing for him to do.
