When I put up the Christmas lights

this year I tested every strand like always and then risked life and limb putting them up. After plugging them in, I noticed half a stand was out in a difficult to reach spot. This angered me because I was out of lights and it was raining so I decided to leave it. Anyway, here it is a week later and somehow it magically fixed itself and is working. I swear there is some kind of evil Christmas light fairy that just likes to mess with me.
