You are working on a project that is very important to you. Some friends drop by unexpectedly. You’d really like to continue working on your project. Do you:

A. Shelve your project, prepare hors d’oeuvres, and apologize for your cluttered living room?

B. Loudly berate your friends for not having called first?

C. Explain that you’re in the middle of an important project and arrange to see them at a mutually convenient time?

D. Ignore your friends and continue working on your project while they are there, hoping they’ll get the message?
