Ha, had a stupid moment- living room lightbulb blew, it knocked out the downstairs lighting fuse. Had to figure out first where my fuse box was. Found that, figured that out. Went to change the lightbulb and went, huh? Oh, weird edison cap thingy. Hmmm... I couldn't quite see easily perched on my stool and I was like, how in the world does this thing work? Had to get on a chair so I was level height before I realized that it was spring loaded. So easy peasy, but a dunce moment! Like first figuring out how the oven worked, the shower, the heating, the dishwasher, the freeview box, DVD player, weird electric lawnmower, etc- all little things that are slightly different than in the states and you feel stupid that you don't know how it works a first glance!
