Waste Not, Want Not

Sometimes what appears as a sad case is, well, funny.
I recently cared for what seemed to be a very sad case. A homeless man, who worked a menial position at a large department store, was admitted for possible stroke.
The man, in is early 50's lived in a tent in the wooded area behind the department store. He bathed in the restrooms at his work place, cleaning his clothed in the sink.
Should he need to heed the call of nature while 'home', the nearest tree or bush sufficed.
He spoke intelligently and stated he had attended college 'up north'.
Alcohol had been his downfall, he drank a fifth of vodka every night, not because he was an alcoholic, but to help him sleep. (His 'stroke' was Wernicke-Korsakoff syndrome, secondary to his alcohol consumption.)

And he wasted nothing.

Every little scrap of paper was utilized. He described his abode as a collection of discarded items.
He said he wasted nothing in his tent.

I can think of only one thing that was wasted in his tent.
