I appreciate the reply, but after thinking about it I think it's more akin to someone having been sold a house only to be told eight years later that the seller of the house knew that if someone tied a shoelace to the front door and pulled on it, then the entire house would explode.
It's more akin to pulling the shoelace, and the door closes on your fingers. Oh no, doors are unsafe, how utterly broken.
Or, more like, if there's an attacker hiding in your house, while you're setting up the shoelace door thing for some odd reason, they could slam the door on your fingers. Oh no, how were we ever allowed to have doors, so criminally unsafe.
Could we consider it a broken doorknob Pierce?
