Sorry, dads. There are more calls made on Mother’s Day than on any other day of the year. That doesn’t mean that the kids don’t want to get in touch with you, though—Father’s Day has the distinction of having the most collect calls made of any day in the year. Researchers are inconclusive as to why Mother’s Day elicits more calls, cards and gifts than its paternal counterpart. It might simply be because it has a 100-year head start, first being celebrated in 1870 while Father’s Day didn’t come about until 1972. Our advice on correcting the imbalance?
