... I had to take out a special insurance when working from home as a freelancer, and share evidence I had done so with my client as -- if someone slipped outside my house because I'd not swept up the snow somehow the company who was paying me would be liable for the insurance claim...

... Yep.

It's for similar reasons why everyone is up at the crack of dawn frantically shovelling snow outside their homes.

Rather spoils the fun of towing the kids to school on a sled when every 5 meters there's a perfectly swept bit you have to drag it across.

Don’t worry. You can drag them on the street! Safety first and all that.
