"I'm a million different people from one day to the next; I can't change my mould, no no." — Bittersweet Symphony
We all show rotating aspects of ourselves, but we remain fundamentally the same. Unless something drastic happens that changes how those aspects present or function anyway.
(Maybe that lyric doesn't mean what I'm reading into it, but it's what I've taken from it. That's a funny thing about art.)
So yeah, I've looked back through comments I've made and realised that I knew something at the time that I'd since forgotten, and seen how smart I'd been - or how utterly cringe-inducing, and known that at some point, that if the cringe is bound to return, so might the smart. Hopefully. Maybe. Please.
There's also the fact that we distil ourselves down for a comment. Present the best side, or the best of the aspect we're going for. Even trolls do this. Unfortunately. So when we look back, not at all in the same frame of mind that we were at the time, it's like looking at the highlights of someone else's life on some other social media, not seeing everything else that's going on besides.
I probably won't remember all the edits and corrections I've made to this comment before submitting the first time. Only time knows how future me will perceive it, should I ever look back.
