The case of the missing index cards

Mr Charm has been walking around the house, searching in every nook and cranny and becoming progressively louder, until I can no longer ignore him.

Mr C: "I swear to God, nothing of mine is in the right place. I can never find anything. All my stuff is lost!"

Me: "What are you looking for?"

"I want my index cards! I have always written things down on index cards. Where are my index cards? I can't find any of my stuff! This house is a mess."

Me: "How about using post-it notes?"

Mr C: "I don't want those! I want my index cards!"

Me: "How about a legal pad?"

Mr C: "Tht's too big! I want to write something down and put it in my pocket. Where are my index cards?"

I decided years ago that I had to either ignore him or kill him.
