I also feel that {ghoS} includes more the traveling part while {chol} focusses on the distance getting smaller. Imagine standing in line waiting for the bus. Everybody is standing still, nobody is {ghoS}ing anywhere. But still, there is this person in front of you who is somehow nervously tripping on his feet. Due to that, he is {chol}ing towards you. You would not say he {ghoS} to you. One other thing considers not so parallel tracks. While the earth flies around the sun, its path is not a perfect circle, it's an ellipse. So during a part of the year, {jul chol tera'}. Also, when driving on the high way on parallel track, your neighbor car may not be parallel to you. If they get closer to your track, I would use {chol}. Saying that a car {ghoS} to you, its intention is to hit you. We may all be wrong of course, and those words are just identical. -- Lieven L.
