Running Theme

This has been running through my head the last few days:

When I get older, losing my hair, 
Many years from now
Will you still be sending me a valentine, 
Birthday greetings, bottle of wine?
If I'd been out 'til quarter to three, 
Would you lock the door?
Will you still need me, 
Will you still feed me 
When I'm sixty-four?

Sigh.
