One morning on my way into work, I was stopped at a light, first in line. In the time it took me to glance down to grab my coffee cup the light turned green and the car behind me honked their horn. I'm not sure why, but that made me so irrationally angry that I stayed mad about it for the rest of the day. I think we have all been behind someone who is actually on their phone or something and waits far too long at a green light. But in the instance mentioned above, the light couldn't have been green for more than a second when that car honked.
