Probably nothing - on a flight from Miami to Charlotte last night. Woman had to check her bag as overhead bins were full. Flight attendant asked woman for her final destination and she said Knoxville. Flight attendant casually said, that's nice, what are you headed their for. Woman replied - house hunting. Flight attendant asked - really, what kind of work are you in. Woman replied - my husband is in coaching and we might be moving there. No - the woman wasn't Cindy Gruden and I never heard the woman's name. But, this is another example of some pre-work being done initiated by someone.
