Sharing the gift of music

Got to the gate hours early here in Atlanta because of the layover, and found a quiet place in a corner, sat on the floor with a cup of coffee and played guitar. A guy came over close, sat down and leaned back and closed his eyes and listened to me play. When he got up and nodded to me, and I nodded back. So this is what if feels like to share the gift of music, huh?
