The importance of finishing high school.

Yesterday I stopped at KFC for a 3PM lunch. I asked the girl at the drive-through window if they took cards, and she said, "We take anything."
"Do you take Confederate money?" I asked.
A few minutes later, she asked, "What's Confederate money?"
I told her.
"It's been a long time since I've been in school," she said.
"It can't have been that long," I said.
"I only finished my Freshman year," she said. "I have two kids. I'm twenty."

She wants to be a physical therapist.
