Well,we do go out...just wrapped in layers upon layers of clothes.
First warm long johns. Then a pair of fleecy joggers.A rollerneck and warm jumper .
Skiing trousers and jacket or a ski suit and gloves,scarf,,thick boots and hat.Then we go for a walk and sometimes take the sledge.But no,when the weather is really bad we only go out for an hour or two at the very most,then go back home and defrost our fingers with hot cocoa and biscuits.
You can do craft kits,read,bake biscuits,watch Tv,play games,tidy the attic,visit with friends.....
You get used to it,I guess.
It´s still magic even if you know how it´s done.
