It IS a beautiful story. Lump in throat comparable to your verklemptness.
Reminds me of the chick flick "Return to Me" with David Duchovny and Minnie Driver, which, I confess, I have among my small, personal DVD collection.
I was never sure if it would be verklemptness or verklempticity or verklempthood or verklemptitude.
I love that movie! One of my favorite parts is when Minnie Driver is set up with another 'transplant recipient' and it turns out to be a guy who had had a HAIR transplant! That guy was one of the writers of the film! His reaction to her pulling his hair was not rehearsed, and Minnie Driver's response was completely spontaneous and hilarious!
