歌词
I always needed time on my own
I never thought I'd need you there when I cry
And the days feel like years when I'm alone
And the bed where you lie
is made up on your side
When you walk away
I count the steps that you take
Do you see how much I need you right now?
When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear to always get me through the day
And make it OK
I miss you
I haven't felt this way before
Everything that I do
reminds me of you
And the clothes you left
are lyin' on the floor
And they smell just like you
I love the things that you do
When you walk away
I count the steps that you take
Do you see how much I need you right now?
When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear to always get me through the day
And make it OK
I miss you
We were made for each other
I forever
I know we were
Oh oh oh oh oh
All I ever wanted was for you to know
Everything I do I give my heart and soul
I can hardly breathe I need to feel you here with me
Yeah
When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear to always get me through the day
And make it OK
I miss you

I always needed time on my own

Do you see how much I need you right now?
When you're gone
The pieces of my heart are missing you
When you're gone
The face I came to know is missing too
When you're gone
The words I need to hear to always get me through the day
And make it OK
I miss you
