That report leaves a promising person who just fkd up having a serious reconsider about concentration on the job rather than out of the door.
Those chips were once very expensive, and they only have a notch on the small face in the ceramic in the middle.
Ah, the value of the chinagraph pencil
Biting the hand that feeds IT
