Don't make an "In Loving Memory" rear window decal and stick it on your car. This is not how I want to be remembered.
Also, do not go to a mall kiosk and get an airbrushed t-shirt made with my face, the dates of my far too short life and angels floating around.
As a 26-year old single person with no dependents, I have no will, but believe me, when I get one drawn up, these will be legal stipulations. And if, after I die, I look down (or up, depending on how things go) on you and see my name on the back window of your Tercel, I promise I will haunt you until the end of your days.
