Some people do not seem to have a mind of their own.They never express their own opinions and they do not make their own decisions.My brother is one of these people.Last night,for example,he was planning to spend a quiet eening at home reading a book.At about seven-thirty,however,his friend Tom dropped by."Let's watch TV tonight,"Tom suggested."Okey,"my brother said.By ten o'clock my brother was tired and sleepy,and I am sure he wanted to go to bed.But Tom was not tired."Let's go out and get a hamburger,"Tom said.My brother agreed.
