Oh, squiggly line....

Oh, squiggly line in my eye fluid,

I see you there, on the periphery of my vision,

But when I try to look at you, you scurry away.
Are you shy, squiggly line?
Why only when I ignore you, do you return to the center of my eye?
Oh, squiggly line, it's all right.
You are forgiven.
