Lester, from old memories and 3 photos over 50 years

First that ancient photo, strumming early moments

Seen through half a century's telescope backward. 

Meeting was too common then to mull sad comments. 

Second, changing view, the sunny midday, fast forward, 

And third, zooming fast, recent, before the final knock. 

In moments the future of decades is glimpsed with a start

While memories of games, music, pranks freeze in shock. 

Discard the telescope, says Lester, it's past time to part.
