I had worked long and hard on this project．Knowing it was finally completed gave me great Satisfaction．“Perfect！”I said “Now, all I have to do is to keep the dogs off it．”I went about setting up barriers using old fence, deck chairs, planters, and anything I could find so as to avoid footprints both on the oil paint and our carpet. It worked perfectly ．
Just before returning to the house and to a much needed shower, I took one last look at this fine work of art．“What is that?” I said．“Where did that come from ?”
Clearly marked and evenly spaced across the entire area, the tiny marks ran in straight lines．I carefully stepped to our flower garden．It was there I found several of the small markings. Now, almost frozen in place by this shocking discovery, I remained in position so as to prevent further damage to my work．Just then, off to my left, it appeared．A chipmunk （花栗鼠）. He was as surprised as I was. We stood there face to face looking at each other, wondering who would make the first move ．
The warm, humid air was now getting the best of me. Sweat now ran freely over my head, and in poor timing into my eyes. I reached up to rub them and when I opened my eyes he was gone ．
My only satisfaction was in thinking that when he returned home he tracked oily footprints into his own home. And , hoping he was married , his wife would not let him live it down for the rest of his life. I stood up, shook my head, laughing about it and walking into my house．
Yes, I tracked oil on the carpet. I am married. My wife will not let me live it down for the rest of my life.
