BUFFALO, N.Y. - At 43 years old, Libby Gaymon went to prom for the very first time on Friday night-- making up for the prom she never attended while she was in high school herself.

But her date was not her husband.

It was her daughter, 17-year-old Alexis, a senior at McKinley High School.

"I'm going to prom," Libby said. "I was asked to go to prom, and I'm going! It's awesome."

A little more than a year ago, Libby was diagnosed with cancer.

Two months ago, she learned it was terminal.

But that did not stop her from going to prom with her daughter.
