This brings to mind the joke (not really SURE it’s a joke!) about why (although, yes, there ARE exceptions) mothers-in-law and daughters-in-law generally do not get along.
Why???
Because deep in her heart, the mother-in-law KNOWS how SHE treats her own husband, and so she has negative feelings toward her daughter-in-law whom she feels is probably her treating HER dear son the SAME way!!!
