It's 2 O'clock in the morning and you awake to find your house on fire. Everyone is out and safe, as are the pets, so you don't have to worry about a living thing. You have time to take 1 thing with you, that 1 thing can be a collection e.g your "J'Pol is king" baseball cap collection. Or it can be one thing, your signed J'Pol angle grinder.
What 1 thing do you take when you are leaving ?
