During our school life,roommates play a big role in our daily life.The  relationship between roommates decide the quality of school life. what are the  important qualities of a good roommate?I think there are three aspacts: good at conmunication,willing to listen and have a tolerant heart.Consider good at conmunication.When we have different opion with roommates,for example,we could express our opion properly and do not hurt roommates if we good at conmunication.For myself,once time,I quarreled with one of my roommates.We haven't say a word to each other for 1 mouth.It's  felt very bad during that time.Later,I thought I should talk to her and deal the problem.So I asked her for a dinner and then told her what I thought,also,she told me what she thought.By conmunication,we undersood each other and have a good relationship till now.Consider willing to listen.Each of us have some troubles during life.As a roommate,we should listen to the sadness or complaints of our roommates and give them courage or help them find ways to deal the problem.Bad mood would affect the atmosphere of dormitory,so take a few minutes listen to your roommate is benifit to everyone.Consider have a tolerant heart.4 or 6 different people from differernt places composed the dormitory.Each one have their own  culture and growing backround.For instance,in China,the south people prefer to eat rice but the north people prefer to eat noodle. You can't compel them to eat rice or noodle. So we should have a tolerant heart to accept the difference and respect the life styles of  everyone.In conclusion,have the three qualities above,a harmony and warm dormitary will belong to us.
