The only person I know who can get the better of Mrs Nick is her SIL.
On Monday they got into some sort of dispute and Mrs Nick came home muttering oaths and declaring that she would "never speak to her again" (which is idiotic, since they live nearby).
Yesterday I phone the SIL (who I quite like) and smoothed the whole thing over, or so I thought.
The SIL called last night. I picked up the phone and she said "Does Mrs Nick never accept any criticism?"
I said, "No, but perhaps you would like to ask her yourself" and handed the phone over. I then left the house and stayed out till VERY LATE.
