"Puzzle" lyrics

What can I say, what do I ask
Now at the door of un-resolving past
Who says that I should be answered more
Each of us faced with our own corridor

And I'm done
And I think I've learned (Ah)
You are a puzzle that always returns (Ah, ah)

When I think I've learned
Oh, you will return
When I think I've learned
Oh, you still return

What can I say, what do I ask (Ah, ah)
Now at the door of un-resolving past (Ah, oh)
Who says that I should be answered more (Ah, ah)
Each of us faced with our own corridor (Ah, ah)

When I think I've learned
Oh, you still return
When I think I've learned
Oh, you still return
