Their jaws had problems, too--they kept falling open for no apparent reason.
She was older than I was. Maybe 18. I knew she was more grown up than the girls at school. She was wearing a sweater as I recall. Uncle Franco and Uncle Eddy would remember every detail.

I saw Gina Lollobrigada on the Ed Sullivan show that night.
I put two and two together . . .
