B12? That's good for me! I like things that are good for me.
I assign blustery days. The kind that depress other people, but can give such a rush. When you walk out into the mildly warm air, expecting to freeze and realizing you won't. The way that the whipping wind pulls your hair out of place, letting it dance in front of your eyes. The sound of crows frantically yelling to one another and the bells of the Tower beating the hour to nearly the same rhythm as the staccato cracking of the wind-driven flag. The paranoic rustling of squirrels on dead twigs. The single leaves forgotten in autumn that still clutch daintily to sleeping branches. The grey sky that promises change and threatens that it will be for the worse.
I love the kind of day that makes you catch your breath in wonder.
