Our house was just made to be decorated at Christmas so it would be unfair to the house 
not to have a little string of lights outside. It's one of those double fronted houses with a pointy porch in the middle, so the lights look lovely running across it.
DS loves it and we live on a road where people drive along to look at the lights, so we join in to the spirit of it without running up the big bill some of the other houses must have.
As for the man who complained that someone looked at his lights. Perhaps he and his wife got into a tradition of putting up lights each year, first just a few, then a few more, then a few more again until eventually the whole house was covered and people would come from miles around to look at it.
Then one year, his wife met someone else and left him. He still put the lights up when Christmas came, hoping to remind her of the many happy Christmas's they had shared. But when he went to see her to invite her to come and look, he saw that the other man had a bigger house with more lights on it and he knew his wife would never return to his comparatively meagre display.
He came home upset and bitter and found wonderingsoul and her children peering with awe at his house and just couldn't stand it, so he was rude to her and she walked away.
The next day he took all the lights down and put them in the bin. But on Christmas eve his wife came back, retrieved the lights because the refuse collection times have all gone to pot, and knocked on the door, begging him to take her back. He was angry and tried to turn her away but she produced the lovely inflatable snow globe that just meant so much to them both and then they realised they were standing under a stray bit of mistletoe he had forgotten about.
They were reunited and redoubled their Christmas light effort the following year and are hoping that wonderingsoul and her two lovely children will return this year so they can share the magic of LED lights and inflatable snowmen with her in the proper festive spirit.
It's entirely possible I have watched one too many channel 5 Christmas movies over the past week or so.
