a rare disorder found in few students: inability to start homework before sleep hours. And regardless of how little or easy the assignment is, it'll most likely require the student to do an all nighter to complete. Easily distracted and can't function properly until the very last minute.
Person A: Did you sleep last night? you look so tired.
