Sometimes...
Sometimes the best thing to do is go home with the emptied-out day in your pocket before it starts to swallow you. And when you get home, then, after eating a little snacky bit, and starting to feel warm defenses coming back in, it should change outside from dull hail to purple skies and soft gray snow falling under streetlights and making cushions on each leaf. When you go out for a crik-crunchy walk in it, it's best to get your feet wet and nearly fall over for looking up and always up and then to meet someone from Arizona who has just made her first snowman on the sidewalk and her first snow angel in the street. It's also a good idea to find tracks (of cars maybe) and hunt them down, all their quotidienne secrets revealed, aha! I make my own tracks too, to see if you can follow them. Mysterious dark tracks, commas, questions, and snakes. If you can write something on the ground at the school yard that is good too. The best is throwing snowballs at a friendly window to make him come outside for a chat.
If it starts to rain after all of that, however, best go back home. And don't throw snowballs at your girlfriend through the screen door. That makes the hot chocolate harder to make.
