Incognito means not waving Hello

I learned that if you are coming back from a morning run and run into the chairman of the conference you are attending and it’s clearly too late to get dressed and back for the start of Day 2 (even if you and your boss decided together to get breakfast and come late) and you think you are now busted, it is really better to NOT wave hello because then you might realized that he had not recognized you in running gear and cap in the first place!

I may not be a candidate for undercover work.  But you knew that.
