(Why did you, why did you, did you go?)
(I'll never know)

Oh girl, I wonder if I'm out of your mind
Are you over me
It hurts and I can't describe this feeling inside

I remember the times
When we were never once a moment apart
You were the only one who captured my heart
Where did it go wrong girl

Why did you leave in September
Thinking the Summer had gone
Now it's a lonely November
Now that my Summer has gone

I'm trying not to think of your smile
But it's always there I find
That I'm okay just for a while

I remember the times
When we were never once a moment apart
You were the only one who captured my heart
Where did it go wrong girl

Why did you leave in September
Thinking the Summer had gone
(Why did you leave me alone)
Now it's a lonely November
Now that my Summer has gone

Now you'll never know how I feel
I'm here for you
If only you could read my mind
You'd always be mine, mine
You'll never know

(Why did you, why did you, did you go?)
(I'll never know)

You'll always be
Someone that I'll remember
Now I know it's time to move on
Now I know

I remember the times
When we were never once a moment apart
You were the only one who captured my heart
Where did it go wrong girl, oh

Why did you leave in September
Thinking the Summer had gone
(Why did you leave me alone)
Cause now it's cold in December
Now that my summer has gone
(I don't know)

And you never know how I feel
I'm here for you
If only you could read my mind
You'd always be mine, mine
You'll never know

Why did you leave in September?
(Why did you, why did you, did you go?)
(You'll never know)
(I'll never know)
Why did you leave in September?
(Why did you, why did you, did you go?)
(You'll never know)
(I'll never know)
Why did you leave in September?
(Why did you, why did you, did you go?)
(You'll never know)
(I'll never know)

You'll never know
