Traveling alone, does it mean that this person must be withdrawn, unsociable and without friends?

Not necessarily. There are many possible reasons for traveling alone:

1. Time coordination problem. Maybe this person's friends or family members can't cooperate in time because of work and other reasons, so they can only travel alone. This doesn't mean that he doesn't fit in or has no friends.

2. Personal interests. Some people just like to travel alone, and they can plan their trips at will, regardless of other people's opinions. This may also be because of his personality, which does not necessarily mean that he is unsociable.

I want to calm down or have a rest. Some people are stressed or have problems, so they will choose to travel alone to relax and adjust their state. This is actually a way of self-healing and self-care.

I want to experience a different trip. Some people choose to travel alone because they can have a different experience from traveling with friends or family in the past and meet their psychological needs of exploring the unknown.

5. Other unique reasons. Maybe this person just came back from a business trip and happened to pass by a place and decided to stay alone for two more days; Or improvise, not plan ahead, and so on.

Therefore, there are many motives and reasons for a person to travel, which does not necessarily mean that that person is withdrawn or unsociable. We should not make arbitrary assumptions or stereotypes. It is still necessary to break the rules and understand the characteristics of each individual.
