Dear Random Horn on the Highway,
What were you doing on the highway this morning, random horn?
You looked like one half of a set of those Cadillac horns people used to (supposedly) drive around with. (I've never seen any on a car in real life, except at Texas football games and amusement parks. And possibly once at a Hard Rock Cafe. On a school trip. Don't judge us. We were in middle school.)
If that is where you came from, where's your other half? Why were you out there all alone?
You were such a strange combination of loneliness, mysteriousness and danger. (If you were a man, I probably would have fallen in love immediately.)
I spent most of the rest of my drive trying to decide what would be a more random sight on the highway: half of a set of longhorn horns (like you) or some sort of brass horn, like a trumpet. On the one hand, a brass horn could easily fall out of a moving truck unnoticed.
On the other hand, this is Texas...
