Central heating might have many advantages but, regrettably, it's put paid to such lovely practices in most homes.
However even modern parents still seem to find ways to keep the magic special. A couple of Christmas Eve's ago, I was shopping in Asda when I met a mum with her two delightful little lads who were wanting to tell me (and anyone else who would listen) about how they'd carefully counted the carrots that they were leaving out for Santa's reindeer, in order to make sure that none of them were left out. Those little boys smiled with their eyes even more than they did with they mouths. It was a moment I'll always treasure.
Merry Christmas! ;-)
