Mother-in-Law Day
Mother-in-Law Day
Mothers-in-law have never enjoyed the widespread respect and devotion that mothers have received over the years, and the rising divorce rate has given the whole concept of in-laws a less permanent place in the national imagination. This may be part of the reason why Mother-in-Law Day has failed to catch on like Mother's Day, Father's Day, and even Grandparents' Day. But many people feel that mothers-in-law deserve a special day of their own, if for no other reason than for their good humor in enduring the many jokes that have been told about them.
