Occasionally, in the stillness of a taxi or an airplane, she would catalog the pleasures she had lost. Cigarettes. Chewing gum. Strong mint toothpaste. Any food with hard edges or sharp corners that could pierce or abrade the inside of her mouth: potato chips, croutons, crunchy peanut butter. Any food that was more than infinitesimally, protozoically, spicy or tangy or salty or acidic: pesto or Worcestershire sauce, wasabi or anchovies, tomato juice or movie-theater popcorn. Certain pamphlets and magazines whose paper carried a caustic wafting chemical scent she could taste as she turned the pages. Perfume. Incense. Library books. Long hours of easy conversation. The ability to lick an envelope without worrying that the glue had irritated her mouth. The knowledge that if she heard a song she liked, she could sing along to it in all her dreadful jubilant tunelessness. The faith that if she bit her tongue, she would soon feel better rather than worse.
