Having multiple light switches in a room and they are not turned right. Like the steps have two switches-one on the top of the stairs and one at the bottom- and the light switch on the bottom is in the up position but the light is off. I will go upstairs and turn the light on/off so the one at the bottom is in the correct position. This goes for what ever room I am in.
YES - this bugs me to no end. I live in a 2nd floor apt, which has one common front door. you open it, and my downstairs neighbor's door is to your right, and mine is up the stairs to my right. there's also a light at the top of the stairs.
There's one switch just as you walk in, which flips up to turn on. Then, just inside my door, is a second one, which flips down to turn it off, and vice versa when I'm leaving. Sometimes though, I won't turn on the light when I go in, so the bottom switch stays down, and when I leave, i have to flip it down to turn it ON, which means when I come home, the downstairs switch is "off" as well. it just drives me batty.
Second lightswitch issue: Houses that have many, and you can never remember what turns what on. My mom's house is like that. She has two by the front door, and a third and maybe fourth, literally around the wall. Which turns on the inside light by the door, the front porch light, the light in the room off the entry, and the ceiling. But do you think I can remember which is for which? Of course not!
Then you move into the kitchen, and on the one wall, there are two, further down the wall are three more. Her house is open from one end to teh other, so the various switches turn on the kitchen, DR and LR lights, plus the ceiling fan. I'm constantly flipping them on and off to get what I want on!
And the same goes for the laundry room/garage. 3 switches, one for the room, one for hte garage, and one for who knows what.
And finally, switches that make no sense. We had some in our old house; the former owner was a builder, and we discovered he had made some interesting fixes, etc. which made no sense to anyone but him!
