What are some of the important qualities of a good roommate?
I think most of us have the experience of sharing room with others.
For instance, when we are at the university, we have to live in the
school`s dormitories with roommates. If I am asked what are some
of the important qualities of a good roommate, I would say they are
consideration, easygoingness and sincerity. There are numerous
reasons for the qualities I choose and I will explore a few of the
most important ones here.
First, the reason why I think my roommate should be considerate is
because of the fact that different people have different habits. For
example, I like to get up early while my roommate doesn`t want to
get up until noon. There exists the inconsistency. Suppose one
morning I get up early, there must be some noise when I put up my
clothes, get down from my bed and go out to brush my teeth and
face. If my roommate is not considerate, she must get angry with me
all the time since we have other different habits. Thus we cannot
live together anymore. So, to be considerate is necessary.
In addition, why my roommate should be an easygoing person is
because I want to make friends with my roommate and let my life
in the dorm be more harmonious. I hope we can help each other
when the other is in trouble and we can chat in our leisure time.
Friendship is the necessities of one`s life I believe.
Furthermore, The reason for my roommate to be sincere is that no
one likes the person who always cheats others. I believe that to be
sincere is not only an important quality of a good roommate, but also
an important quality of a good person. That is a usual way of
evaluating people. I would also like that to be my criterion for
choosing my roommates.
From the above you might get the idea that sincerity, consideration
and easygoingness are important qualities of a good roommate.
