I was thinking about this the other day as I was walking down the sidewalk. (I also thought it would make an interesting thread. ) What side of the sidewalk do you default to? That is, do you walk on the right side of the sidewalk naturally or the left. Does this preference depend on any situations? I'm also curious to discover if this depends upon the side of the road you drive on in your country (i.e. right side in the U.S., left side in G.B.) I prefer to walk on the right side of sidewalk but if I notice someone coming right at me I'll slide over to the left (obviously to avoid running into them). I was in London this Spring for Easter but I can't recall which side of the sidewalk I used.
