第一段I think it depends on individual habit.Some people like to leave things around,they can find what they want in their messy places,if we put their things in order,they can not find what they want sometimes.We should value their habit,we can not say it is right or wrong.
第二段But as a student,we should not leave things around.Even though we cannot say it is right or wrong,it is not a good habit.We should develop good habit.If we leave things around,we would give other people bad impression,they would think we are lazy,and our parents would criticize us too.So we should put our things in order,and keep a tidy living and study environment to give other people a good first impression.
