Who Knows Dear? (Quem Sabe, Um Dia?) de Carlos Lyra

How do you like that?
You showing up just like that
It's been a long time dear
Since you've gone, disappeared
How I wonder
If we had ever been young
Today you're more than lovely
And I, more bohemian
I would love to
Go over certain moments
Too bad they're simply over
But just as I was saying
Who knows if there's a day
In our future?
Who knows, dear…
