Our son told me the other day that his wife (i.e. our D-in-L) had been slightly puzzled that she had not received a Mother's Day card from us.
"Slightly puzzled" does not describe our own reaction to that news: we've never sent her one before (the grand-kids are now 12 and 9), and woulld never dream of doing so: she's not the mother of either me or my wife! We've never, ever, sent MD cards to anyone except our own mothers (and probably not even then, since MD cards hadn't really been invented then!).
WE are (well) Up North. THEY (son and family) are in Kent. Is there some kind of "cultural difference"? (On this particular point, I mean: we know already what a cultural _gulf_ here is between Down There and Up Here.)
