Bed-Making Time Saved

There were no mourners
For hospital corners.
On the day they died from fitted sheets...
The toss and billow
Of a pull-on sheet...
With cleverly sewn-in permanent corners...
Taut as a sailboat's jib in the wind
And quick as pulling on underwear.
Now all the bed-makers, from that day on,
Have much more time 
To vacuum and dust.
