Former US president Abraham Lincoln put it graciously when he wrote that all he was, or ever hoped to be, "I owe to my angel mother", while writer James Joyce shared a similar, if more bluntly-delivered, message.
"Whatever else is unsure in this stinking dunghill of a world a mother's love is not."
Closer to home, and this century, Prime Minister Jacinda Ardern last year paid tribute to her mother on what was her own first Mother's Day since toddler Neve's birth.
"Just when you thought you couldn't be any more grateful for your mum than you already are, you have your own child and your appreciation for your mum keeps growing with every day that passes."
We want to hear your stories about the person you call mum this Mother's Day.
Tell us why she's special.
Send your responses to cherie.howie@nzme.co.nz before 10am Wednesday May 6.
And make sure to include both your full names and a photo, either of mum alone, or with you.
The Herald will publish some of the tributes online and in the Herald on Sunday on Mother's Day next Sunday.
