The moment you realized you needed glasses
I realize it doesn't always happen that way.
But it did for me. I was in a movie theater in Tucson, Arizona. It was either late 1979 or early 1980. I was in my mid-20s.
A friend and I had just seen "Kramer vs. Kramer." I asked if the closing credits were out of focus. They were not.
How about you?
