"Diary" A bad night

Today was Monday the most painful day in a week. Although I only had four classes on Monday, I felt tired when I finished the classes at three o'clock p.m. After I finished my class and took four hours to rest in dormitory, the bad thing was happened when I took a shower.
My cell phone rang loudly so that my roommate took it up and talked to the caller. Because this was a man's voice, my roommate thought the caller was my father and told him I was taking a shower and I would call him after the shower. Strangely, the man insisted I needed to take the phone. The man's attitude was very impolite and he spoke in Taiwanese. Unfortunately, my roommate was not good in Taiwanese, so she didn't know how to deal with the thing. She cannot help but she gave me the phone.

(next was the conversation, all them was interpreted straightly .)

"Hello?" I said.

"Hey!" a strange voice said, and then, I understand one thing.

"Hello?" I said again.

"Hey!" he said again, too.

"...Who do you want to speak? " I asked politely.

"xxxxxxxxxx. Give the phone to the phone's master in hurry! The price of the call was expensive!" he said with many impolite word and was very impatient.

"This is my phone.You call the wrong number." I said.

"xxxxxx! Don't say that! Give the phone to him(her)!" he didn't accept the thing and reflected very angry.

"I say you call the wrong number!" I raised my voice.

"Hey! The call was expensive! Hurry up!" he still ignored what I said.

"I don't know who you want to speak, the phone is mine!" I started anger and impatient. Because I was in the middle of taking a shower, I felt so cold that I wanted to finish the ridiculous call.

"Really? Then I call again to check, ok? " he said with sarcasm and distrust.

"Ok." I said and cut the phone immediately.

Of course, the cell phone didn't ring again in the night. But my mood was worse than before. This was the first time I shouted to stranger.
