Dido

Like a ghost don't need a key
Your best friend
I've come to be
And please don't think of getting up for me
You don't even need to speak
When I've been here for just one day
You'll already miss me if I go away
So close the blinds and shut the door
You won't need other friends anymore
Oh, don't leave home
Oh, don't leave home
And if you're cold
I'll keep you warm
And if you're low just hold on
'Cos I will be your safety
Oh, don't leave home
And I arrived when you were weak
I'll make you weaker, like a child
Now are your love you give to me
When your heart is all I'll need
Oh, don't leave home
Oh, don't leave home
And if you're cold
I'll keep you warm
And if you're low just hold on
'Cos I will be your safety
Oh, don't leave home
Oh how quiet, quiet the world can be
When it's just you and little me
Everything is clear
Everything is new
So you won't be leaving with me
And if you're cold
I'll keep you warm
And if you're low just hold on
'Cos I will be your safety
Oh, don't leave home
Because I will be your safety
I will be your safety
I will be your safety
Oh, don't leave home
