My 14-year-old daughter, Maggie, and her best friend, Joannie are fans of 60’s music.

They recently got front-row tickets to attend a Peter, Paul, and Mary concert in our town.

When they returned home from the concert that night, I wanted to hear all the details of the concert.

My daughter says, “Mom, during the show, we looked back an saw hundreds of little lights swaying to the music. At first we thought people were holding up cigarette lighters. Then we realized that the lights were the reflections off all the eyeglasses in the audience!”
