I don't get it. Mind you, I'm not a big movie fan but I see so many people who, when watching, seem to require a blanket. That includes my Californian grandson who normally only dons a shirt when going out.
Last night our other, Scottish, grandson was staying and, clad in his fleecy dressing gown (I was lathered in just a thin shirt) asked for a blanket in order to watch TV.
