The truth is, you will wake up and realize the old life you had, as you knew it, is gone. And the truth is, you will want it back. You will want it back with all your heart, and it will hurt, because that is what loss feels like.
The truth is, even if you did find a way to go back, things are never going to be exactly as they were because you aren’t exactly the same person anymore. Neither are the people you left behind. There will be parts of you that you recognize, the core of you that makes you who you are, like your love of books, of adventure, of the absurd, and your ability to put things down and walk away for good. There will be parts of you that you will lay to rest, like your need to writhe unabashed under flashing lights with strangers, to stumble home with addled wits and equally addled friends. There will be parts of you that are new and surprising, like your increased capacity to compromise and the true extent of your caring. The truth is, the march of time is inexorable, and the change it brings is inevitable for you, and for everyone else you know.
The truth is, you will get tired. Of each other. Of the sameness. Of the monotony. You won’t always like the same things, and want to do everything together because the truth is, sometimes sharing space – your space – with another human being gets claustrophobic.
