If all else fails you can write a card, but remember–it has to be sincere. In the words of Anna Jarvis, founder of Mother’s Day herself:
A printed card means nothing except that you are too lazy to write to the woman who has done more for you than anyone in the world. And candy! You take a box to Mother—and then eat most of it yourself. A pretty sentiment.
The fact of the matter is that Jarvis ultimately grew to regret founding Mother’s Day at all. It became vastly commercialized by the candy, flower and greeting card industries. In her eyes, paltry gifts you pick up as an afterthought on the way home do nothing but cheapen what the day is supposed to mean.
