According to the person leading my spin exercise class, today (Monday, March 20) is the first day of spring. Spring is a great time to have a general clear out and give your domestic and professional spaces a good tidy up. I recall the time when I was up on my ladder cleaning the leaves out of the guttering and had to remove a bracket from the wall to repair one of the joins. The bracket was secured with four screws, three of which were flathead and one crosshead. After getting the first three out with the correct screwdriver, I proceeded to use the same flathead screwdriver to leverage out the fourth screw, only to slip and scrape my knuckles down the brick work.
