At hostel, my roommate was a very selfish person and would avoid doing anyhting that did not concern him.  A few of us prepared lunch together and had decided to share the work.  My roomate had promised to do the same but I had to wash the bowls everytime after dinner.  I tried to wait and thought that he would realize his fault.  I did not want to tell him to do the work as he is a university student and ought to have self-respect.  He disappointed me and so every time I saw him I tried to avoid him and did not want to keep any contact with him.
