Apparently Tommy, the caretaker at Catty Library, had a difficult week getting the place cleared out for the building works. Every day he asked Julia if he should get on with taking down the shelving she told him no. Finally, on the Thursday he said: "I'll get on with the shelves now." "No, don't do that."
"They'll need taking down before tomorrow."
"Leave them be. The company that's going to be installing the new shelves will take them down."
"If the shelves are still up how will the builders replace the floor?"
