That is how it usually begins. "Excuse me, can you tell me where the Tobacco Chewers Anonymous meeting is?" "Excuse me, sir, can you tell me where that sign-up-thingy-for-the- obese-kids is?" People who are lost or clueless often spot a mailman and assume he knows where everything is. I have learned over the years that if you say you don't know, they think you are lying and give you some more information as if that will jog your memory. It is fun to help when you can. But it can be frustrating when a person persists after you admit ignorance. Since I am working in a town where I do not live and only cover a small part of the county, I often do not know the answer to "no not the BIG concrete company, the one close to a retirement home or something". So I give them an answer. "Down that-a-way about 2--no almost 3 miles and take a right. At the next stop sign take a left and keep going until you see an old school bus parked up on a hill. Bear right just past that." Depending on how obstinate they are, I may send them 10 or 12 miles. The secret is to say it with confidence and send them far enough away that they can never find you again. Thankfully, I was able to help this friendly driver today. He was looking for the Taco Bell.
And just like that, he was gone!
