Well my wrist aches, you might think that that was from being up a ladder with a Bosch 24V Drill driver for the 1000 screws I put in. Or possibly it was the post job completion celebration.
To be fair mate...why didn't you just save all this headache and employ a plasterer to board the ceiling?
It is a plasterers job after all...
Why are more and more people forgetting that nowadays?
