You start to light her cig - a - rette, And all at once you love her; You've scarce - ly talked, you've scarcely met, But all at once you love her. You like her eyes, you tell her so, She thinks you're wise and clever. You kiss good - night and then you know, You'll kiss good - night for - ev - er. You won - der where your heart can go, Then all at once you know.
