I'll just add a bit of (I believe not apocryphal) cultural history.

The observance of Mothering Sunday had appparently fallen into disuse in the UK by the early twentieth century. However, during the second world war, the Yank GIs stationed here were often looked after by local families and, to show their appreciation for their adopted 'mothers', revived the custom of Mothering Sunday. Being rich and all (and tall, strong, handsome, cleancut young well-fed men), they began to lavish presents upon the 'mothers during those few years. The mothers, I presume, discovered they were on to a good thing, and no doubt used all the guilt tactics they could to ensure that their real children kept this up.

So the mothers in the UK have the Americans to thank for Mothering Sunday. (At least, that's what I've heard.)
