Someone asked how you've been.
You said you're getting there. That stopped being true months ago, and you said it anyway.

Getting there is the safe answer.
Nobody asks a follow up about getting there. Say you're different and somebody might want to see it.

So you collect proof. Quietly.
In case somebody asks you to show that you've changed. Nobody has asked. You collect it anyway.

You're waiting for the day that makes it official.
There isn't one. This kind of change happens on an ordinary Tuesday and tells nobody.

Getting there isn't modesty.
It's an exit you leave open, so that if this doesn't hold, you never said out loud that you'd changed.

Next time, let the sentence stop at I'm good.
Nothing after it.
