When I was a freshman in college my mother gave me a poetry textbook that she had had in college, and I’ve enjoyed it constantly since. One of the poems I first cottoned on to is by Carl Sandburg, and it reads:
“Look out how you use proud words.
When you let proud words go, it is not easy to call them back.
They wear long boots, hard hats; they walk off proud; they can’t hear you calling –
Look out how you use proud words.”
