You know what the problem with lights controlled by more than one switch is? No? You should. It's that the two switches controlling the light end up in the wrong position. When I flip a lightswitch, I want it to go up when I'm turning a light on and down when I'm turning a light off. This is the proper way to do things. When you've got two switches hooked up to the same light, though, this gets out of whack. You flip it on with one switch, and then you flip it off with another, and when you go to use the first switch again, you end up with a switch that's down when the light's on and up when the light's off. This isn't right. It bothers me.
It's quarter after four in the morning. Is my OCD showing?
