Are "Thank You" cards dying out? What happened to manners and curtesy?

So no Christmas ones then?

This week my 5 year old and 3 year old sat down with glittery gold 'special' pens at the ready, and wrote out their Thank You cards.


Whilst Santa did, of course, deliver a fair few presents, he also delivered presents that family and friends had selected for the girls (assuming they'd been good and Santa deemed it appropriate that they received them!)

On that basis, the eldest sat and wrote out 12 separate Thank You cards.  And very proud of her I was too.

Only it was rather difficult to find 'Christmas specific' cards on which to write.  Now I didn't have the time, energy or inclination after the week that was Christmas to make them from scratch, so in the end, the only ones I could find in the shop were these. (see picture)

The 'Hello Kitty' and Peppa Pig' ones aren't even proper cards.  It turns out they are 'postcards' with barely any room to write a personalised note.  The others aren't card's either, they are 'letters'.

So what happened to Christmas Thank You cards?  Did everyone buy out the shops stock?

Or do we just not say thank you in this way anymore?
