Like a ghost don't need a key
Your best friend I've come to be
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
If you're cold I'll keep you warm
If you're low just hold on
Cause I will be your safety ...
