Really You've Never Seen a Horse

so this really confused me last night as i was driving across town. i'm in the fast lane behind a car that was driving down the road like a bat out of hell. when all of the sudden they slow down and match the pace of a truck hauling a horse trailer. this kind of pissed me off cause i was in a hurry and wasn't in the mood for these people's nonsense. after about a minute i was looking for a way to get around this car and horse trailer but i was trapped. so anyway after about this minute the person in the passenger seat took out their phone and started taking pictures of the horse. really, i mean have you never seen a horse? but it gets even better (at least in my opinion). after a few minutes they finally finished making a photo journal of this life altering experience and they speed up. then they move over into the left lane and i looked over. they looked like a little kid in a candy store or someone who has seen big foot (ok so it didn't get better). don't get me wrong i love horses, they are incredible animals. but really do you have to create a problem to the flow of traffic on the freeway to get a picture of a horse's head poking out of the trailer?
