I don't know how to say goodbye

The leaves must turn
The wind must blow
The heart must learn
When it's time for the heart to let go
But when I think of you
My heart knows why
I don't know how to say good-bye

The world moves on
With no regret
And though you're gone
There are feelings I'll never forget
So I remember you
And though I try
I don't know how to say good-bye

The house we used to share
Still looks as if you're there
And I won't change a single thing
Not even the wedding ring I wear

The evenings fall
Much harder now
The stars grow small
And the moon seems so different somehow
But every time I think of you
The moon and I
Know you're the only reason why
I don't know how to say good-bye
