The windows were closed, I swear!

The other day, I hollered at a guy in a truck trying to cut me off on the entrance ramp to the highway. The two lanes merged into one, and he waited until the last possible minute to attept a merge, but the spot he tried was already taken. I swear, he was only 6 inches from the vehicle. The windows of the vehicle were all closed, so I'm certain the guy in the truck didn't hear me. The problem is that I was riding the bus home and everyone on it heard me yell, "MORON!!!"
