why do airplanes fly alone .?

I knooow . Pilots and even geniuses could easily answer my title-slash-question . But read on .

Our dismissal time today was uber early . Why .? Well , simply because we have our periodical exams today . We normally have it quarter by quarter . And normally , if our dismissal was not this early , my friends and I would usually go home together . We'd walk to our respective houses destination by destination . Ha ha .! But on days like this , when the sun is shining pretty high on the horizon and it's f*ck*ngly hot , some of my friends would rike a trike home . But since I didn't want to spend for my transportation when I could just walk home , I asked animeartist if we could walk together . Since their village is on the left side of the highway , and I would turn right on the highway , she agreed , It's fair for the both of us . At one point or the other , we'd have to part ways . Unless , we live in under one roof . Ha ha .! We talked until we were to part ways . Simple goodbyes were said . (We don't like super emotional goodbye's when it comes to this situations . We'd only be apart one night . One night .) And as I walked home , alone , I had a hell lot of time to contemplate . Mostly about everything . But as I was walking down the peaceful , quiet , noiseless street , something in the sky caught my attention . An airplane . I know what you're thinking . It's not the first time I saw an airplane . But it's the first time I thought about it deeply . Why do airplanes fly solo .? I have never seen two airplanes flying side-by-side . Maybe because literally , they would be too close for comfort and would crash to each other . But why do humans feel alone when they fly through life solo .? Why do we need someone to fly with us through the storms and strong winds that come our way .? Maybe that's why we are specially created by Him . We need someone in our life to be with us through the good times and the bad times . Unlike airplanes , we cannot live alone .
