For the second time in several weeks, the tire pressure indicator flashed in my face on the dashboard of my car. The tires looked fine, but I took the car to the tire center near my home. Confession: over the weekend, I somehow managed to drive over a curb. The guys at the tire center checked everything out. They couldn't find a problem except for one tire that showed no damage but lost some air. Keep an eye on it, they said. For the second time in several weeks, there was no charge for the services.
Before I returned to pick up the car, I stopped at the local drug store and purchased a giant bag of miniature chocolate bars (135 of them!) to give them in thanks.
