So far the only blunder I envision is blaming your wife for putting the hot pan in the sink. Obviously, if you were being more help the situation would never have happened. My suggestion is to make it clear that the poor quality sink provided by the manufacturer is the primary issue. Replace the sink with one of "better quality" and make it clear that you are sorry for not being on hand to catch the situation before it occurred. Perhaps even show her the note you will be posting complaining of the quality of sink in the rig.
Satire....maybe...maybe not.
