I am a boy, can I sleep in the dormitory with bare arms?

Sure! It's not good to sleep in the dormitory with bare arms.

Because everyone in the boys' dormitory sleeps with bare arms, you are not open enough to get along well with everyone. It is very sad and ridiculous for a man to be afraid to show his body.

Of course, if it is in winter, it is another matter. The most important thing at this time should be to keep warm.

Therefore, when everyone sleeps with bare arms in summer, they must sleep with bare arms.
