You guise, I do not understand why people cannot manage to turn off lights. It baffles my mind.

I'm the last person to leave the office 98% of the time. Everyday, I have to go through every single office and turn off lights. I did not turn them on. I did not enter these rooms. These are other people's offices. And they cannot turn off their lights. It's a switch by the door. It takes half a second. It drives me bonkers.

Granted, I was in the deserts of Southern California during the Enron energy crisis, rolling blackouts in the middle of summer. I've had the $400 electric bills for a 700 sq. ft. apartment. I am very conscious of lights being on. BUT STILL! You leave, therefore lights go off. It is not a difficult concept.

How about you guys. What very simple things annoy you to pieces?
