I got the question today from my Godson who is on the cusp of believer/no believer that this year Santa cannot get in because they have had a woodburner fitter, so how is he going to get in.
It was a direct challenge.
Thankfully his mother on the other side of the room heard this and ran off. I fudged the answer and 5 minutes later she was back as if nothing had happened with an old metal key in a jewellery box.
This is a magic key that will be left outside the front door
He's really not sure either way.
