I had one of those heart warming moments myself on our trip last week, but it was specific to the moment.
We were seated in the third row to see Festival of the Lion King, with is one of my favorite shows in Disney to begin with. I was right behind an elderly lady in a wheel chair, her daughter and grandson sitting next to her on the end of the bench. She was a typical frail looking person, but let me tell you, she was clapping, bobbing her head, snapping her fingers and loving every minute of the show. Alot of the performers would swing by and give a high five to her grandson (who was probably about 4 or 5), and I imagine that must have delighted her as well.
For how hot of a day it was (pushing 95) and how much it must have took for her to be there, she sure enjoyed herself for that show. I'm not ashamed to admit it brought tears to my eyes. I hope at that age I too can still be enjoying Disney World as much as she was.
