Discretion: The trait I value most in others, and spend a great deal of mental energy trying to maintain myself. I dislike breaking confidence as much as I dislike discovering that it's happened to me. With very few exceptions, I put my trust in the saying, "Three people can keep a secret if two of them are dead." As a result, I have too many secrets.
Decanters: I love everything about them. I love their curves and the feel of cool glass in my hands. Their big heavy stoppers and the sound they make when you slide them out to sniff the brandy/port/sherry/Madeira. The refraction of light from their walls and the shimmer and sparkle of the liquid inside. The brass labels that are sometimes hung round their necks.
Dielectrics: Without them, none of this computer or internet stuff upon which I am not afraid to admit a certain component of my happiness depends would exist.
d20: Dice are wonderful to hold in general, but these are special because they invoke many happy hours spent playing role-playing games.
Diatoms: The images of phytoplankton that I saw when I was a small child ended up being part of the inspiration that drove me to become both a scientist and a painter. After reading to us about Van Leeuwenhoek and his wee beasties, my grandfather bought my cousin and me a microscope. I don't think a single corner of the garden, whether it was soil, plants, small insects or stream water escaped inspection. He sliced up thin slivers of roots and branches for us, since we were too small to be trusted with Xacto knives. The delicate structure and symmetry of cells never fails to mesmerize me.
Dim sum: Tiny packets of neatly wrapped tasty food that you eat with chopsticks. Delightful!
Dictionaries: Particularly ones that make idiomatic and cultural distinctions. The Dictionary of British Slang has saved me from putting my foot in it many times.
Dragons: I was born in the year of the dragon. According to the Chinese zodiac, I am a fire dragon, which has often been used by my family as an explanation of my terrifying temper, although I suspect my parents' example has a great deal more to do with it. . I adored the river dragons in Spirited Away. I own a few precious things that feature dragons, though I don't usually display them or wear them visibly. They're a private symbol for me. And now I have one less secret.
If you would like a letter, ask! I promise not to use X or Z unless you really want me to.
