There I learned that the modern holiday was first celebrated in 1908 by a woman in West Virginia, USA, who held a memorial for her mother. It was she who campaigned to have it recognised as a holiday, and though she was successful in 1914, she was disappointed by its commercialisation in the 1920s. I guess that must be round about the time Hallmark took a hand.
Regardless of the day’s origins, there’s nothing wrong with honouring a beloved mother, right? Happy Mother’s Day! This one’s for you, mum.
