Sixty

I grumbled a little bit to myself today when my kids were playing with a friend who was singing aloud lyrics to a song he's evidently heard numerous times on his parents' car radios.  I wasn't ready for my kids to be learning words like these.  Then I listened a little more carefully. 

The friend sang: I'm sixty and I know it.  Da-da-da.

Rachel sang: I'm sixty and I know it.  Da-da-da.

Nathan sang: I'm eighty and I know it.  Da-da-da.

Then someone sang: I'm ninety and I know it!  Da-da-da.

I guess I don't need to worry too much.  If they don't have a context for understanding something, they work it around to make it make sense.  Darlings!
