Thanks for the sentiment Mak, but despite my age I have no kids so don't qualify.
I do however have a father still going strong at 88 (probably on his PC at this very moment).
I'm a little surprised that it's the same date on both sides of the pond, (probably because it's an invention of the big multinational corporations), unlike Mother's Day which derives on this side of the Atlantic from "Mothering Sunday", which is part of the religious calendar, and is on a completely different date from yours.
