Go for a walk.

A nice calm walk is in order. You depart from your house and decide to leave your car behind. Today, you're going to be healthy and enjoy the fresh air of the city. Well, as fresh as city air can be. This ought to keep your nerves at rest. The sun is bright, though it's not too hot. The day is young with plenty of time left to enjoy it. Even better, you have nothing planned.

You walk several blocks away from your apartment. Various shops are set up in this area selling things from shoes to hats. As you make your way down the street, it actually becomes rather crowded. Some people you recognise, and some you don't.
