This afternoon as I was returning from class, I noticed a couple of the building maintenance guys hanging out by the window near the elevators. I nearly moved in to push the button to alert the elevator that it was time to have it's way with me, when it dawned on me that perhaps those guys weren't just hanging out; perhaps they were waiting for the elevator! With this brilliant observation to keep me in check, rather than desperately pushing the elevator button like it'd been a while, I squinted at the light over the button to see if it had already been pressed.
As it turns out, it's difficult to see if the indicator light over the button is lit up when the sun is coming through the lobby window of my building. Of course, you could determine the status of the elevator by the presence of people around the elevator, as I did today, but such people are only present 98% of the time. The other 2% of the time, pressing an already-pushed elevator button in my building on a sunny afternoon does not guarantee that you're a tool.
It appears that I was unfairly critical of people that I don't know. Needless to say, I'm wearing an expression of shock on my face. I could apologize, but apologies without corrective follow-up are just meaningless filler. I will absolutely do this again.
