作词 : Collins, Smith
I begin to wonder, baby
What's goin' on when 
I'm not at home
I begin to wonder, baby
I know you ain't there all alone
Every time 
I have to leave you, woman
I wonder who's takin' my place and turnin' you on
I begin to wonder, woman
Why I worry everyday
I said, I begin to wonder, woman
Wonder why 
I feel this way
I be home early 
Tuesday evenin'
Better hide your part-time man away
I begin to wonder, woman
Why we wasted all this time
I begin to wonder, baby
Wonder why we didn't see the signs
What we did, we've now forgotten
What we had, we've left behind
