My watch had been running 10 minutes slow for a few days. To remind myself that it was consistently 10 minutes slow I put little pink sticker on the watch face, so I'd remember to add 10 minutes onto the time it showed. A simple solution, I thought.
After about three days, Mr FD saw that the sticker was still there.
"Is your watch still running 10 minutes slow?" he asked.
"Yes," I replied.
"Why not just move the hands on 10 minutes then?"
An even simpler solution!!
