Ed,
Probably, what they write and what they actually do, are two completly differen't things Ed. Sometimes it's just like letting off a bit of steam, when writing on the Forum, Like MM did with the scam mail he recieved.
I don't think there's many that would knowingly Embarass there wife in public, for no real good reason, Chinese or otherwise. Anyway, If she thinks your going OTT she will tell you, ...don't worry about that haha!!
Now, think of another senerio, like your wife getting heated , maybe over the quality or cost of something she wants to buy. She would not give Face a second thought in such circumstances, because she will know that she is right and will fight (verbaly) for herself. I know , been there too many times!! ...hahaha!!, But then i just watch and think ....this and she, ...is really funny!! Don't worry about this Face thing too much, it's been blown up on here way out of preportion.
