This is just a friendly reminder that today is Mother's Day.
The day to honor mother's was thought up in 1910 by Sonora Smart Dodd, after listening to a Mother's Day sermon.
In 1912, Anna Jarvis trademarked the phrases "second Sunday in May" and "Mother's Day", and created the Mother's Day International Association.
Jarvis made the conscious decision to place the apostrophe after the "r" in the word mother so the word would remain a singular possessive not a plural possessive commemorating all mothers in the world.
This is also the spelling used by U.S. President Woodrow Wilson in the law making official the holiday in the U.S., by the U.S. Congress on bills, and by other U.S. presidents on their declarations.
However you spell it, just remember to give mom a little extra love (and perhaps some flowers) today.
