For those countries where the driver is on the right hand side of a vehicle, when two people are walking toward each other, which side do they gravitate to in order to pass?

Just wondering. I have noticed that here in my little part of the US (although there is little walking) and during my stay in a large metropolitan area people tended to move to their right in order to pass and that moves to the left seem to confuse the oncoming person somewhat; not that they can’t adjust but just that they seem a little uncomfortable.
