Books: I read when I have to or at a whim. Oh, books on music.
Though not really a book, I enjoy Wikipedia surfing. Surprisingly
profound children's books are also particularly enjoyable reads.
Books on language, I dig those so much.
Movies: Les Parapluies de Cherbourg, Le Fabuleux Destin d'Amélie
Poulain, Le Science des Rêves, Les Demoiselles de Rochefort, Jeux
d'Enfants, Eternal Sunshine of the Spotless Mind, Amadeus,
Shakespeare in Love, The Notebook, LOTR: Return of the King,
Chronicles of Narnia series, Moulin Rouge, Amour
Shows: Family Guy, Mary Shelley's Frankenhole, American Dad,
Nigella Lawson/Jamie Oliver/Jacques Pépin cooking shows and I don't
watch much TV. Toddlers in Tiaras and Breaking Amish are my new
Music. It's what I do :). Oddly specific classical genres, though
weird contemporary/popular music sometimes works.
Food: Canned foods. Especially seafood. And pickles. I enjoy
gastronomical explorations of all sorts!
