Stunned man gets caught spying on an unsuspecting woman

This guy has been sneaking around trying to catch someone off guard for weeks but never expected what happened today when he sees their wife leaving work right behind closed doors as they walk toward each other down another hallway than usual. The momentary distraction allows them both enough time together before one of them makes sure everything is fine again by locking up those double front entrance doors tightly! And yet after all these years married life still surprises us every now then; especially when his eyes meet hers under such circumstances revealing something entirely different compared against reality seen through casual observation alone. What does her reaction say about who she really is? Will he learn anything new tonight or will old habits die hard even among couples like them living happily ever since forever?
