My thought of the day is:
Because I don't have a cell phone I'm always looking where I'm going, so I myself can avoid colliding with other people in the street. However, I've witnessed many individuals running into each other simply because they are immersed in their little toys. At first I found it quite annoying, I still do a little, but now it's quite hillarious. I suggest that if you are feeling bored, go seat at a park or coffee shop and observe people as they collide with one another... All I can hear is the circus music in the background as the monkeys keep running into each other, having seemingly lost their perception and peripheral vision.
