Yeah, it's called heartbreak. About 2 billion songs written about it.

When the world turns its back on you, you turn your back on the world.

Real bands save fans.
Real fans save bands.

The problem is not the problem, but the problem is your attitude about the problem.

Don't do anything stupid until I get back.

You get hurt, hurt 'em back.
You get killed? Walk it off.

I solemnly swear I am up to no good.
