How Lucky I Am, How Stupid I Am

I have a friend, let's just call him MAS. Don't get puzzled. MAS is not AMS though they share a character: being SMART MOUTH.
Yesterday afternoon at my office, in the middle of the quietness of working and drowsy situation suddenly my coworker shrieked, "Awwww what does MAS mean, telling things like this!!??!"
"Hee... what things?" I said. He pointed his finger to his computer screen. A chat window. Aha! His wife told him whatMAS said to her before, "X was doing really really well for choosing you as his wife." X here is my coworker.
Wahahaha... Then I sent an instant message to MAS, told him that I knew what he said to X's wife. He just laughed. And I asked him, "why you never said to me so... Why you never told me that ams did the right thing for choosing me as his wife?"
He laughed and laughed and said, "well, in your case... I should say you're doing the right thing for choosing m raul as your husband." What??? x(
Well, actually I do think so. MAS was perfectly right. But why oh why he did not kindly say it the opposite way, that I am such a blessing for ams? Just to make me happy? Ha ha, if he said so, I certainly would laugh... not because I was happy but because I'd think that he was ridiculous.

And let me tell you what ams thinks about whether we choose the right partner for the rest of our life.
When I do something stupid, when I make mistake, I'll say, "Haa how stupid I am." And when ams is around, he'll say, "yaaa you're so stupid, indeed." Oh, I won't be mad at him because I know after that he'll say, "you're so stupid for choosing me as your husband." And he know that I'll say, "silly, of course I chose you... you're the smartest man I've ever met in my life." The conversation already become our ritual. Now, don't vomit please.
