People may be single for two reasons. One is that they don't want to find a partner and want to live easily. The other is that they are not good enough or have problems and can't find a partner.

I remember that I have a brother who is single. He is over 30 years old. In fact, if a person wants to fall in love, it is easy to get rid of it if she is good enough. But maybe my brother just wants to be a single aristocrat, with a car and a house and good family conditions. He felt full and his family was not hungry, so he never fell in love. Maybe one day, he will change his mind.

There is also a friend who is not very familiar. He is almost 30 years old. He is not in love. He feels very introverted and a little stupid. He may not catch up with girls at all, or he may not catch up with girls at all, resulting in his being single.
