How come when you write on a page and the pen stops working it won'twork again on that spot after fixing it

The ball-point of the pen requires friction to roll it and make it apply ink. Once you try to use it(showing it's already getting gummed up inside and requires even more friction than usual) and drag the dry ball over the paper, you're basically smoothing the fibers in the paper down (picture running a steamroller over a field of hay, but on a microscopic level) and greatly reducing the friction.

Long strokes to get the ink going help with this a lot.
