In some countries, more and more adults choose to continue to live with their parents after they graduate and have found jobs.
Do the advantages of this trend outweigh its disadvantages?（社会）
Nowadays, increasing number of adults who have been graduated and found jobs can be seen that they choose to continue to live with their parents. From where I stand, I firmly believe that it is a positive trend.（4分钟）
On the one hand, some people believe that a lot of disadvantages can be seen if more and more graduated and working adults continue to live with their parents. They have some good points to support their view. Firstly, conflict can be cause because of different habit. For example, many adults who are just graduated may like to have abundant night life like going to bar at night, whereas parents are older and would like to have a healthy daily habit such as getting up early and going to bed early. Thus, different life style may cause conflict and badly affect each other. In addition, living with parents may make the young adult rely on them. As we all known, parents always care about their children very well, such as making a good meal for them in everyday and giving money to support them. However, this may cause them hard to be independent, which means that adults may probably become lazy and can not manage themselves well. Thus, it is not good for adult to live with parents after graduated and found jobs.（20分钟）
About this phenomenon, I consider that the advantages outweigh its disadvantages. The main reason is that living with parents can decrease the pressure of living. One fact is that the cost of buying new house is becoming more and more expensive, so living with parents can save a lot of money and do not need to care about where to stay. The other reason is that living with parents can look after each other. As for parents, they may having some diseases and may become lonely due to the increasing age. However, if their children can live with them, they can be accompanied and cared about. In the other hand, after a hard work in a day, adults can just go home to have a meal and relax instead of making meal by own.（32分钟）
In conclusion, considering that living with parents can look after each other can reduce the pressure of living, I firmly believe that the advantages of the trend outweigh its disadvantages.（34分钟）（结尾还需要再论证嘛？还是直接点名自己的观点就可以了？）
