Are 'Friends' Electric? (The Dead Weather)

It's cold outside And the paint's peeling off of my walls There's a man outside In a long coat, grey hat, smoking a cigarette Now the light fades out And I wonder what I'm doing in a room like this There's a knock on the door And just for a second I thought I remembered you So now I'm alone Now I can think for myself About little deals and issues And things that I just don't understand A white lie that night Or a sly touch at times I don't think it mean anything to you So I open the door It's the friend that I'd left in the hallway 'Please sit down' A candlelit shadow on a wall near the bed You know I hate to ask But are 'friends' electric? Only mine's broke down And now I've no-one to love So I found out your reasons For the phone calls and smiles And it hurts and I'm lonely And I should never have tried And I missed you tonight So it's time to leave You see it meant everything to me
