1. Introversion: Some people are naturally introverted and may prefer solitude and thinking to social activities. This doesn't mean that they don't like to associate with people, but they are more inclined to think deeply and reflect on themselves in less social occasions. 2.

Use of social media: Social media in modern society enables people to keep in touch with friends and family without face-to-face communication. Some people may use social media to avoid face-to-face social activities, such as chatting with friends on social media instead of going to parties or activities.

3. Protect personal space: Some people may prefer to protect their personal space and privacy and avoid too many social activities. This doesn't mean that they don't associate with people, but they are more inclined to protect their privacy in less social occasions. 4.

Stress and anxiety: Social activities may also bring stress and anxiety. Some people may avoid social activities because they are worried about their performance in social situations. 5.

Lack of interest: Some people may not be interested in social activities, preferring to be alone or engage in other personal interests. This does not mean that they don't like to associate with people, but that they are not interested in social activities.

It should be noted that these reasons do not apply to everyone, everyone has their own unique personality and background, so the reasons for avoiding social interaction may also vary from person to person.
