Cultural differences 10/15

Hi, what are you going? 

In Japan, yesterday seemed to be a holiday. I noticed it today. So, today may have been start of the hard week for many people in Japan.

In my school, Monday is review day, so new lessons start Tuesday. Many new classmates came to my class. 

The difference of culture

Today, I found something like notes in toilet room.

I was surprised at bottom left one. Is there anyone who evacuates in such a strange way???🤪🤪🤔🤔

I didn't understand and I thought that cultural differences is interesting😇
