Every country has its own culture.
Even though each country uses doors. .Doors many have 21 functions and purposes which lead to 22 differences.
When I first came to America, I noticed that a public building had two different 23 and they had distiFnct functions. 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 24 the building. This was new to me, because we use the 25 door in south Korea. For quite a few times I failed to go out of a shopping centre and was embarrassed.
The way of using school bus doors was also 26 to me .I used to take the school bus to classes. The school decided that when the driver opened both the front and back doors, 27 who were getting off the bus should get off first , and students who were getting on should get on 28 . In south Korea, we do not need to wait for people to get off. One morning, I hurried to the bus ,and when the bus doors opened, I 29 _tried to get on the school bus through the front door. All the students around looked at me, I was totally 30 ,and my face went red.
