There is usually some half-completed and quarter-thought-through construction project in my living room. A few projects back was a raft built from soda bottles, later rowed down the Charles river for a charity pirate-battle. Now I'm building equipment for the chemistry and physics experiments previously run in my kitchen. Please don't tell my landlord.
A friend from home (CA) and I went to a different burrito place in Boston once a month for four years on the quest for Boston's Best Burrito. It's like being the Don Quixote of burritos.
The only coffee-table book I own is called "The Legacy of the Puppy." It's 200 pages of pictures of puppies and I go flip through it whenever I'm in a bad mood. It never fails to cheer me up.
