I'm the opposite of claustrophobic (claustrophilic?). Small spaces really calm me down.
Best bed I ever slept in was on a schooner in Puget Sound -- a bunk built into the side of the ship. The only way you could get into it was to bend way over and sort of roll yourself in. Needless to say, there was no way you could sit up in bed. But it was so cozy and wonderful.
Also my last name is hyphenated, and the conversation starter that is usually attempted when people learn that -- "What are you going to do when you get married?" -- is one of my biggest pet peeves.
