Sleep
Closing each eye is something that the peoples do before they sleep. The peoples can’t sleep with both eyes open and they can’t sleep with just one eye open either. Peoples have to close each eye before they can sleep.
みん
ねむ
None
The reason you want to sleep is because all the other peoples were mean (みん) to you. They were so mean that the only way you could get over it was to close your eyes and sleep. You just want to sleep.
