At the Paint store

AFTER NEARLY AN HOUR of "just a little more white, two squirts of blue, a dash of black, perhaps a tad more white," the paint-store clerk got my gallon to the exact shade I wanted.

 With a sigh of relief, he pounded the lid on.

 Now what do I do if I need more paint, I asked. 

Don't come back here, he begged.

Like a fool I asked , What if my wife does not like the color?

He looked me in the eye and smiled and said , there is a paint store down the street.
