The First Impression of My Roommate
It was my first day at the institute. I got into the building where l was going to live, and looked door after door for my name. At last I found it. In the room, there was already a student making his bed.
After we said "How do you do " to each other, he continued his work, paying no more attention to me. I looked around the room and found that it had been thoroughly cleaned. No doubt it was he who had done it.
I looked at him. He was thin, short and dark. His hair was like a bundle of straw. His dirty clothes and tired look told me that he had had a long journey. His clothes were made of cheap cloth, and he wore a pair of rubber shoes, which were very unfashionable. He was not a very smart freshmen at all.
The second time he spoke, his accent tom me that he was from the south. "Shall I help you to get your luggage from the office "
