As it was he borrowed our ladder (well it's not our ladder really, it belonged to a deceased relative of Carl's and is being stored in our cellar- God only knows why) and leaned it against the plastic guttering of the shed. After it slipped and he fell off, I appointed myself his assistant and anchored its base and got myself showered with brick dust while he used this fabulous drill- a bit like an apple corer- to take a great plug of brick out of the wall. I thought our walls were two bricks thick- but they aren't; they're three!
The best thing about having workmen in, is the hour or two after they've gone. The pressure lifts, you have your space to yourself again and everything is so, so quiet.
