David Lyttle offers three scenarios for receiving a "wrong number" phone call. Since reading his blog two days ago, I've had two such calls, and responded with David's implied advice to ask what number the caller is trying to reach -- uncommon sense and uncommon courtesy that helps the caller AND avoids the possibility of a repeated interruption. Doing this consciously, I noticed that instead of getting "sorry's" from the callers, I got "thank you's." I also discovered that I liked the latter more than the former. To help yourself, help others.
