After a long day of being called upon to visit an endless series of horses and cows with sore legs, I finally returned to the animal clinic.

Although exhausted, when I discovered I had a slow leak in one of my truck tires, I drove over to get it fixed at the service station.

The mechanic knew immediately he was dealing with a tired veterinarian after I carefully explained to him that my truck seemed to be lame in the right hind tire.
