Straight
If you live in a big city and just hate it when people bump into you on the street, there is a way you can get around that and make others move for you. By keeping a good posture and staring dead straight ahead of you, people will actually move out of your way as you continue on your direct path.
People will see that you are not only focused but probably in a hurry and will get out of your way in most cases. So walk with confidence, keep your shoulders back and chest out, and your vision dead ahead. This little adjustment could save you a lot of time weaving in and out of crowds.
