Modern Etiquette

Today on Modern Etiquette we discuss the following problem, which I'm sure all of you have faced at least once in the past year or so. If you have to be in the front yard at four in the morning in only your underwear and someone else walks by, do you:
a) Run inside?
b) Ignore them completely and go about 'whatever' you were doing?
c) Engage them in conversation?
As always our expert panel will be discussing these possibilities with any others that may occur to us.
