内容：Recently，I had a little quarrel with my roommate.
Last weekend，I went on a business trip. When I returned home，I found out that my roommate had left my computer on.I had bought it last year，and it had been in bad condition for a long time.I was very careless.When I wanted to use it again，I didn't even turn it on. My roommate said "I turned it on."However，he had not finished his work，either.
We argued about it for a while.Finally all he said was :"Forget it，then."
"OK."I said.Then I picked up the computer，and turned it on .
My roommate suddenly asked me， "Have you checked the warranty(保修单)?"
"No."I replied.
"Warranty says the computer shouldn't be turned on."
I read the warranty again.As a matter of fact(事实上)my roommate was right. The computer company had offered a one-year warranty(质保) to all the buyers of that computer.But it didn't mean on warranty(质保)on the computer.
I became angry immediately(立刻).How could my roommate bear to see the computer on，when he knew it broke down .Furthermore(再者)，he had turned it on without my permission .
After a short while(片刻)，he came in ."I'm sorry.I want to say"，he began， "I have known for a long time. I didn't think you'd be angry.I'm sorry."
I couldn't say a word.How could I tell my roommate I was angry .
