I keep this painting around the studio to remind myself that some lessons are really painful.
This is a detail of an oil sketch I did many years ago. In those days I was a bit too "casual" with my work and set this painting on the floor next to my easel to dry.
One day I discovered that I had managed to splatter paint all over it - which was dry and could not be removed.
Still . . . I left this work on the floor until a week later - my full-time-dog and part-time-art-critic evidently mistook this piece for a fire hydrant.
Sarge (named after John Singet Sargent) never did that again - thank heavens.
So the point of this story is: Treat your work with the respect it deserves and don't leave it laying around where it can get damaged.
