How do you know when you are getting older?

[Chancie]

People tell me that I look pretty young for my age; I just turned 50.

But, I was in the supermarket the other day, and

There was a very proud papa with his beautiful adorable infant, and

She was wearing a tiny lace trimmed dress that was obviously a family heirloom, and

I asked her if she would like to be in my math class in 14 years, and

The papa said, If you're still teaching, you mean.
