Maybe Mike, but laughter is also a cure (I was just thinking). Lately, when my W will do something that I think is either to completely rile me or complete rubbish, I tend to laugh, I guess it's almost sarcastic laughter, but it's better than saying anything. I will often follow it with a bit of a sweetner of something amusing that we have between us.
However, that's not every time, stuff I'm belittled about my boys I find almost impossible to control.
