I have had a load of scaffolders working for me this year and though i don't always have time to do it, it's good to watch them in the midst of the graft & momentum, because they will fall into a rhythm on a straightforward job and it does become a flow.

As soon as his men leave the building, the floor where they had been standing collapses. Had they still been inside, they would have plunged into the fire below.
