Walking New York is a bit like driving underneath a tunnel. You can walk through a crowd of people and come out unscathed. But the chaos works only if you keep moving. If you stop or hesitate you’ll get stuck. Hello claustrophobia.
It’s easy to avoid the tunnel or the pack of people as long as you’re up for taking an alternate route that’s inconvenient and takes more time. It’s also not how the world works. The world works en masse, not in a single lane dedicated to you.
If you’re going to go places you’re going to have to get used to crowds, and on occasion, wait in line. If those crowds are anything like they are in New York, all you need to do is keep walking straight through. It moves, naturally. The most difficult path is sometimes the most favorable one.
