It's never my intent to make people cry while I'm playing my guitar and singing at the red kettle for The Salvation Army. It wasn't my intent, but it happened.
I was playing through some of the songs in my Bob Dylan songbook when she came out of the store pushing a cartload of groceries. I saw her start to exit the foyer area and then hesitate, then she pulled her cart off to the side and waited. My attention wasn't really on her, so I didn't see what she was doing until I finished the song.
When I finished the song, I rolled my shoulders and stretched for a bit (it gets to be a long afternoon) and I saw that she was still there, standing next to her cartload of groceries, crying.
I asked if she needed anything.
She said "no," and thanked me for playing. She said that her husband (now dead) used to play that song for her.
It's not my intent to make people cry with my singing, but sometimes it happens.
