You'll never see my face, but I'll be there. You'll never hear my voice, but I'll be listening.
When you pick up that letter, and read "I'm always watching you, I'm right behind you." You somehow look right past me and ask yourself "Where? Where?!"
But don't worry, I'll have your back.
Don't worry about that murderer living next door to you. I'll take care of him next, you won't see him for long.
And when the day comes when you have to move. Don't worry, I'll find you again.
