One gray line after another

One gray line
after another.
It doesn't look like much now,
but I keep drawing
One gray line 
after another.
I curve the lines,
loop-the-loop them.
I flick my pencil
I erase 
and erase.
One gray line 
after another.
I'm finished,
but I'm only getting started,
This is not just a drawing
it's a story
ideas filling up my mind,
then I go to write,
one word
after another...
