The Christmas lights which inaccessibly adorn our rather high front-garden tree inexplicably went dark a day or two ago.
I struggled with possible explanations. A bulb gone (they're LEDs!!)? Damp in the plug from this interminable rain? A fuse blown?
Today it finally stopped raining so I ventured out to take a look - and try stuff. Result? The lights still don't work but I am completely convinced that I now have no idea at all as to why.
Oh, and I have a cold coming on ...
