"lean to + upside down small claws" picture yourself inside a little wooden Lean-to. You are scratching graffiti onto the roof - you have a running correspondence with another graffiti artist. He writes something insulting about you, then you write something insulting about him. You are using a Small set of Upside-Down Claws to scratch your latest RESPONSE on the roof of the Lean-to. If you are in a Lean-to with a set of Upside-down Small Claws, you must be writing a RESPONSE. TO RESPOND.
