You know when you were a kid, and there was one special thing that you desperately wanted for your birthday; whether it was a new bike, or a pony, or a video game system, or a Red Ryder BB gun. You dreamt about the specifics of that new bike, you knew how the handlebars would feel. You could see the exact color of the pony’s mane; you visualized playing all of the coolest games on the console; you could already hear the pop that the gun would make.
And yet, when your birthday rolled around, your parents had done their best, but what they got you was a semi-reasonable facsimile of what you had asked, hoped, and dreamed for, but it just wasn’t quite right to one degree or another; or worse yet, they got you something completely different.
