cracks in the sidewalk

when i log into my email account there is a little bar that shows how much of my allotted space my email currently occupies. on the lower left-hand side of the bar is 0%, while on the lower right there is a little 100%. there is nothing in between and i find this disturbing. i mean, there is inifinite space between 0 and 100% and having no further demarcation frightens me.

a lot can happen between 0 and 100%.
