I had just moved from an apartment to a house in the same small town. One day at the grocery store, I used the last of my personalized checks bearing my old address. The cashier examined the document and asked if everything on it was correct. I assured her that it was, and she started to put the check in the cash drawer. But then she inquired again if everything was accurate.

"Why do you ask?" I responded.

"Because," she replied, "my husband and I moved to this apartment yesterday, and I don't remember seeing you at breakfast."
