One Boot Was Made For Walking, Apparently

Can someone please help me understand the phenomenon of the mysterious one shoe on the side of the highway, please? Has anyone else ever wondered how or why this happens? I mean, how does one shoe end up on the side of the road? What happens to the other shoe? For instance, on my way back home tonight, I passed 3 different shoes on the side of the road. One was a black clog-looking shoe, one was a white high-top tennis shoe, and one was some sort of brown loafer. WTF? I mean, if they were kids’ shoes, I could imagine a 2- 3-year-old kid tossing one out of the window just because. Or a 4 –5 year old kid tossing a sibling’s shoe out the window after a backseat fight ending with mom shouting for each of them to “ be quiet and look out of their own windows.” While complying with mom’s demands, the sibling is still retaliating against the other by tossing a shoe out of their window. I can see that. I have a younger sister and when we were growing up, we had our fair share of backseat brawls that ended in us each having to “look out of our own windows” in mom’s car. But these appear to be adult shoes, and I really can’t imagine any possibility of how one shoe gets ditched to reside on the side of the road. However, I feel like whoever loses their one shoe to the D.O.T. should win some sort of “Idiot” prize. After giving this a great deal of thought (like 5 whole seconds), I’ve come up with the perfect thing. The prize these people should be awarded is the one sock you pull out of the dryer that lost it’s mate somewhere along the laundry process. These people only have one shoe now so they only need one sock. Man, I shock myself with my problem-solving ability sometimes. I should probably try out for the U.N. or Peace Corp or something.
