The title.
Feel free to ask me stuff. I’m in Scotland, born in Canada. I’ve been a mason for coming on 15 years. And my favourite dinosaur is…not really a dinosaur…the Stenopterygius species. because they’re tubby not quite dolphin looking (apparently) reptiles.
You clearly pay them well enough for the good advice you get.
Tunnel under the wall if you can, light a giant fire, or your not explosives.
