character development

In the book the Laundry News Mr. Larson who is the teacher of Cara was a very lazy and not very caring teacher in the beginning of the book. For example, Mr. Larson always never gave them homework and never let them learn anything because he says " the best way to learn is for them to teach themselves" which I agree with because you always have to practice something by yourself but not like this! Also Mr. Larson, all he does is read a magazine and drink coffee and the only time he gets someones attention is when he hears a kid scream, hear a glass break, and when someone cries. The only way Mr.Larson teaches the kids is ripping off articles in his magazine and pin it on a bulletin board so the kids read it. After a while Cara made a newspaper called the Laundry News (based on her last name) with different articles and one cheeky article about Mr. Larson which made Mr. Larson really mad! Ever since the news paper happened Mr. Larson started to teach and gave them homework and assignments which was really weird for the class! but Cara was happy that Mr. Larson taught them which was all that she wanted.
