Voldemort's Flying Circus
Interlude
Our lives are defined by our choices. Every single time a choice is made, even as simple a choice as whether one should floss their teeth with lemon-flavoured floss or mint-flavoured ones one fine morning, an alternate reality is created. For example, had that person chosen lemon-flavoured floss, he would not have been torn apart by a savage Peruvian Golgothan the next day, whose only fear is, conveniently, lemons. Unfortunately for that man, he didn't, thus resulting in his brutal demise. However, due to the mere possibility of his choosing to use the lemon-flavoured floss, an alternate reality is created, one where the Peruvian Golgothan smelt the man's lemony breath and ran away after squealing like a pig. The man would eventually go on with his life, thanking whichever deity he worshipped—which, in this reality, happened to be the great juju up the mountain— for his amazing good luck, only to be strangled to death forty-two years later by the very same lemon-flavoured tooth floss.
However, there comes a time when something so highly improbable happens, one which the universe had never considered, that the universe sneezes. Literally. Another alternate reality is then forcefully created based on this highly improbable choice. And when said highly improbable choice causes another highly improbable reality to be highly improbably created, it sets off a chain of highly improbable events in said highly improbable reality.
Trust me, you do not want to live there.
Of course, the offending reality which created this highly improbable event is deleted from existence to prevent any future offences. After all, it is hard work to manage all the alternate realities— black holes are formed on the face of the galaxy, a sign that the universe has suffered yet another mental breakdown. The person who holds the record for number of mental breakdowns inflicted on the universe is Harry James Potter, mostly due to all the highly improbable deaths he suffered. One notable death includes being decapitated at the end of his first year at Hogwarts School of Witchcraft and Wizardry for sticking his head out of the moving Hogwart's Express while waving goodbye to his friend Rubeus Hagrid, only to have his head separated from his neck when the train entered into a tunnel. The universe, who had never thought that anyone could have been so daft, suffered a mental breakdown, causing a black hole to be formed in the star system Sol. The planet Pluto was reduced to half its size in this tragedy. Decades later, an astrophysicist by the name of Dr. Neil deGrasse Tyson finally realised this indiscretion and Pluto's planetary status was revoked. Centuries after, the dwarf planet Pluto committed suicide by hoisting itself into that very same black hole. Yes, Harry Potter remains to be the bane of not only Tom Riddle Jr.'s existence, but also the bane of the universe.
