I think I hear people mostly use the phrase "going down the street" instead of "going up the street" or "going on the street"
It is common to hear that :
I was going down the street when I saw her
in songs or movies.
I don't think the word down has something do to with a inclination, declination or direction.I feel people use it even they walk on a plain road/street.What exactly does this sentence mean?
So what is the difference between :
I was going on the street when I saw her
and
I was going down the street when I saw her
and
I was going up the street when I saw her
