There's this bus that runs near my work. Like many buses, it has a little matrix of LEDs on the back that can spell out a few characters. This particular bus chooses to display two letters: "HA". And they blink on and off every couple seconds.
So most days I end up behind this bus, and it laughs at me. Derisively, I can only assume. In my mind, I hear the cold, cruel monotone of a Speak and Spell™ mocking me: "HA... HA... HA... HA...".
The bus. It knows my secrets.
