Age and Health Departments

Man on our way out of the Health Department: Whoa!  Are all those kids yours, or are you babysitting?

Me, trying to smile graciously: No, they're all mine.

Man:  Are you serious??  How old are you, like 21?

Me:  Nope, not 21.

Man:  Younger?  You can't be older.

Me: I really am.

Man:  I'm 23--are you my age?

Me:  No, not your age.

Man:  Younger, then? [shaking my head as I try to corral the kids to the car] Older?  No way.  How old are you?

Me:  Older than you.  Have a good day.

Man:  You kids take care of that mom of yours!  Keep her looking young.

Did that conversation seriously just happen?  Surely after you've asked five different ways and I still haven't told you my age you'd give up...
