This thing in my mouth

12 lines of questionable edibility

As i sat and ate,
My thoughts drifted from my plate,
Thus my sad story.

I just ate away,
Bite after bite, chip by chip,
It slowly clears off.

I should have thought more,
Eating wasn't such a chore,
Still I sit and mourn.

Could i be this dumb?
I just sat here and nibbled
Away my whole thumb.
