Keeping Score, by Grandpa Jim

As we creep up on our four score,
We sometimes wonder how many more.
The little ones, and some are 4,
Frolic unaware of all that's before.
Their parents near a mere two score
And give us hints of what's in store.
Their parents, in turn, near score three
And look back now to return our care.
As we approach the thought of five,
Arm in arm, with far less drive,
We see quite clearly, we've been alive.
