But What Did I Know?

What did I know?
Everything about absolutely nothing.
Ideas and wisdom created by what I believed
was the worst experience ever.
And I thought you were different.
Good for me. Nice. Caring.
But you haven't grown up.
And I guess I haven't either.
I expected to get swept off my feet.
All I got was dumped on my ass.
And you moved on.
You moved on two nights later.
Before I knew what had happened.
Before I knew you were even considering it.
I should have expected it,
seen it coming or something like that.
But what did I know?
