2. Pay attention to the weakness of human nature. Human nature has many weaknesses, and everyone has some. It's not that someone is bad, but where is human nature. For example, most people are vain and jealous. You may have a good family, but if you spend money lavishly, others will think you are showing off, even though you used to live like this. What is normal for you may be different for others. There are similar grades and the like, all of which are the same. Actually, this is a normal phenomenon. You need to pay due attention to the feelings of people around you so that it won't be too painful.
If you really have a difficult roommate, don't force yourself. To put it bluntly, everyone happens to live together. Being able to get along is fate. But after all, there are differences between people. If they don't deal with each other, that's it. If you push yourself too hard and think about it every day, then you will feel more and more uncomfortable if you are too sensitive. Just jump out and don't take it too seriously.
4. The human heart is a bottomless pit. Not only for roommates, but also for everyone. If you don't want to be nice to others, others will be nice to you. Don't try to be honest with everyone, but keep the bottom line. Only when you have the right expectations of people will you not be disappointed by your high expectations.
