Today morning, one of my friend made me annoying.

...

She is younger than me about 8 years old but I think she is maturative and nice.

...

I have been down with her and we decided to go to the Busan for watching a baseball game with another friends.

...

We have to prepare tickets(train, baseball game) and sleeping place and etc.

So yesterday morning, I sent a message to her "Did you check the booking state? If you book the tickets late then maybe we will not get them"

...

But she just sent a message "~~~. Do check E-mail."

...

In Korea, usually most of people use polite expressions when they talk to older people than themselves and  and do not order to them.

(Maybe most of all countries are also like Korea.)

...

So I just thought maybe she had a mistake...

...

But today morning she sent me another message again like that and I was very angry.

So I said to her "Please do not tell me again like this. I feel very angry and bad."

But she said to me that she could not understand why I feel bad.

...

So I said to her "I think you are one of my close friend but you were very impolite to me today. I think we have to be polite each other more closer."

But she could not understand what I said so I could not say to her any more.

...

I can not understand her either.... -_-
