"I have to be fair with my wife"

Below conversation took place between me and boss (male) on one fine day...

Boss: "My mom is not very well lately. She just had knee surgery. And she is getting old. I am worried about her."

Me: " Oh.. is she living with you and your family?"

Boss: "No. She lives alone."

Me: "Oh... " 不解 expression shown on my face. Not because the fact that she lives alone. It is the fact that you tell people you worried about your mom, and she is ill, and very old, and yet you let her stay alone.

Boss continued : "I have to be fair with my wife."

Fair?????????????????????

What the hell is this????????????????????????

How is taking care of your mom being unfair with your wife by staying together?

I know 家家有本难念的经, but what you said is what you think. Unbelievable a son will think like this. But then again, I am not surprised. My nearby also got such one fresh example lah. Yiu.

See lah? Prove another - son is really 没有心肝. (This will piss off a lot of people, but, so far 90% of the time I see this happening).
