The mere thought that there's another man out there who knows your woman and spends more time with her than you do is something no man wants to even imagine. That there's another man elsewhere who pulls chairs for her, opens doors and brings her flowers almost every morning.
Now. There actually is, such a man. In her office. She leaves the house sulking because you haven't paid the monthly water bill on time, she's not talking to you and showing all the attitude in the world because you didn't give her chama money last Saturday. But the moment she steps in office! Her mood suddenly changes and her best day at work begins.
