What are the advantages and disadvantages of living in a dormitory and living alone?

The advantage of accommodation is that everyone will help each other, have a good time and have a lively atmosphere. The disadvantage is that sometimes the atmosphere is too lively and sometimes it will be annoying. If you are unlucky, you may even steal your things or reveal your privacy if you meet someone with bad character. And the learning atmosphere is not good. The advantage of living alone is that privacy is safer, and there will be no incidents such as classmates lacking things. But sleeping at night feels a little unsafe and will be afraid. In case of an accident, it is not easy to ask for help immediately.
