Most older people do that, since we were taught to walk on the left. Lately we have seen a lot of younger kids walking in the same direction traffic is moving.
If you do that, just make sure you watch out for cars pulling out. I had a friend that would have hit someone if I had not been in the car. She was pulling out on a road and was turning left. She was only looking to her left, when she started pulling out.
A guy walked in front of her car from the right. She would have hit him if I didn't scream stop.
It might have been completely her fault, but it really doesn't matter who is right when your dead. It made me completely understand the reason for going with traffic.
