You're standing at a busy intersection Downtown watching the traffic cruise past with metronomic tedium. As the seconds stretch to minutes, you think, "Wait, didn't I hit the crosswalk button?" It's definitely been minutes. Press. Nothing. Press, press, presspresspresspresshithithit. Nothing.
You might be there for a while, because the obnoxious reality is that the crosswalk button is pretty much bullshit. It's nice to have that illusion of control over the situation, but depending on where you are, there's a strong chance that it's literally not connected to anything.
