How to fight lonliness - Wilco

How to fight loneliness
Smile all the time
Shine your teeth to meaningless
And sharpen them with lies

And whatever is going down
Will you follow around
That's how you fight loneliness

You laugh at every joke
Drag your blanket blindly
Fill your heart with smoke

And the first thing that you want
Will be the last thing you'll ever need
That's how you fight it

Just smile all the time.
