Every country has its own culture.
Even though each country uses doors, doors may have   50  functions and purposes which lead to   51  differences.

You have to push the door with the word “ PUSH ” to go out of the building and to pull the door with the word “PULL” to   53  the building.

Students who were getting off the bus should get off first, and students who were getting on should get on   56  in South Korea. We do not need to wait for people to  57 . One morning I hurried to the bus, and when the bus doors opened, I  58  tried to get on the school bus through the front door. All the students around looked at me. I was totally   59 , and my face went red.
