There are ten things I cycle through depending on different circumstances. Is it sunny? I’ll bring a notebook. Is it rainy? I could sog it, unless I’m indoors. Am I going to get into a building? Better bring my keys, or not if not. There are tons of circumstances. The only constants are money, which I keep in the pants/skirt/jacket/shirt pocket of my dominant hand when possible, and my glasses, which I am either wearing or have in my opposite pocket when possible, the former currently safe from pickpocketers in my breast pocket of what I’m wearing underneath my sweater (unless a pickpocketer wants to go that route).
