Frankly, I think Mark needs to be a little more authoritative with Steph on the show. When she starts getting out of line, with her gender issues for instance, Mark needs to give her a stern look, maybe point his finger in her direction and snap his finger and say "OK Steph........thats enough!" just to show her whos boss. After all, he's a man and she's a woman, so its pretty obvious she over-steps her boundaries too much already.
No sense in letting that stuff get too far out of hand.
Next thing ya know, she'll start thinking she is equal or some nonsense.
