I hate to spoil your Mother's Day, but take a look at this:
Years after she founded Mother’s Day, Anna Jarvis was dining at the Tea Room at Wanamaker’s department store in Philadelphia. She saw they were offering a “Mother’s Day Salad.” She ordered the salad and when it was served, she stood up, dumped it on the floor, left the money to pay for it, and walked out in a huff. Jarvis had lost control of the holiday she helped create, and she was crushed by her belief that commercialism was destroying Mother’s Day.
[. . .]
Jarvis soon soured on the commercial interests associated with the day. She wanted Mother’s Day “to be a day of sentiment, not profit.” Beginning around 1920, she urged people to stop buying flowers and other gifts for their mothers, and she turned against her former commercial supporters. She referred to the florists, greeting card manufacturers and the confectionery industry as “charlatans, bandits, pirates, racketeers, kidnappers and termites that would undermine with their greed one of the finest, noblest and truest movements and celebrations.”
[. . .]
Jarvis’s ideal observance of Mother’s Day would be a visit home or writing a long letter to your mother. She couldn’t stand those who sold and used greeting cards: “A maudlin, insincere printed card or ready-made telegram means nothing except that you’re too lazy to write to the woman who has done more for you than anyone else in the world.” She also said, “Any mother would rather have a line of the worst scribble from her son or daughter than any fancy greeting card.”
Kind of a typical complaint, though. Once-a-year celebrations are natural targets of card makers and florists, so it would be unusual if they didn't highjack a holiday. And visiting Mom or writing her a letter or in general paying more attention to her just one day a year seems about as superficial as sending a card.
