Coziness. Cozy robe, cozy blanket, cozy socks (very important to the whole state of being cozy!), a cozy spot on the couch, and a Thin Man movie (William Powell and Myrna Loy as Nick and Nora) on the T.V. Mmmm...so cozy! A dog on my lap could possibly make it even cozier.
My harps! When I feel stressed, which is most of the time, I can sit down and play myself into relaxation. Even my cat comes and sits at the base of the harp while I play. Fortunately, on the harp, even the wrong notes sound good!
But I really love the sea, especially sitting on the shore when I am alone and watching and listening to it in all it's different moods. Wild wet and windy, or calm and quiet, they both are lovely to me.
