I can't think of anything in life, that I've done yet, that is a single, solitary magical moment of transformation.
Sure, I graduated high school and college, but in both cases, there was no diploma in the fancy case that was handed to me with a handshake. I had to pay fees, return library books, wait for the finals to be graded and recorded, and only then was I magically turned into a B.A.
Sure, I got married last year. But to do this and have the state recognize it, a couple has to apply for a marriage license at least three business days in advance. Then they must file said marriage license, which does not happen on day of the wedding (unless you get married at noon on a Tuesday) and it takes a month or so to be recorded. Only then are you magically bound by law. (You could just skip out on filing the license, have a party, and go your merry separate ways, which I find odd; shouldn't "they" bind you to it at the ceremony!?)
Sure, I've been hired at cool jobs, but I've also had to wait to start working at them. Sure, I've turned 21 and waited for that first legal drink... but even then, they let me drink at 11 PM at Montana AleWorks in my hometown, even after seeing the date on the license. An sure, before that wedding I got engaged, but we're a collaborative type of couple; it wasn't insanely out of nowhere, ya know what I mean?
Much like these milestones, I'm on the precipice of owning a house today. At 5 PM, or a few minutes before, the county recording agency will change the title from someone else's name to mine and John's. But before this, we've applied for a loan, signed all the documents, signed some more, send even more to the banks... and at 5 PM tomorrow, the supposed magical moment of transformation will happen.
But alas, we won't get the keys till an hour later. Or on Wednesday, or actually as late as Thursday at 5 PM, since we're such darn nice buyers, so it is another contribution to the hum-drum-ness of real living and the lack of a true magical moment of transformation.
For what it's worth, I think having a baby biologically must be the only true moment of transformation; you may think of yourself as a mother or a father before that, but in a single moment, you become the mother or father of that baby. So THE single magical moment, at least, does exist for some folks!
