Graduation day.

It's one of those things where you're lost in an old environment.
You're leaving behind a community where you first grew up.
You leave it to join a new one.
That new will become old as well.
After a little bit, you have to leave that one too.
A nest away from a nest.
You're afraid you'll forget who you are once you leave home
and come back to it.
Home is when the people you're surrounded by help you figure out who you are.
Who you're not.
Who you thought you'd be.
Who you grew up to be.
Who you ended up being.

And if that doesn't tell me who I am, I don't know what will.
