Some young people might not talk to others because of social anxiety. They worry about being judged or rejected, which makes them feel nervous in social situations. They might also overthink what to say and how others will react. If they've had bad experiences in the past, it can make them even more hesitant to communicate, especially in big groups or new places.

Many young people prefer digital communication over face-to-face interactions. They feel more comfortable texting or messaging online because it gives them more control over the conversation. They can think about their responses and express themselves better in writing. This way, they avoid the pressure of having to respond immediately, which can be stressful in direct conversations.

Some young people might not communicate much because they're focused on their personal interests and hobbies. They enjoy activities like gaming or reading, which don't require interaction with others. These solitary pursuits can be more fulfilling for them, and they might not share common interests with their peers. They value their alone time for creativity and reflection.

Cultural or family influences can also play a role in why some young people avoid communication. They might have been raised in environments where open expression wasn't encouraged. Cultural norms or family dynamics might have taught them to be self-reliant and independent, making them less inclined to engage in open dialogue. They might also be influenced by introverted family members or role models.
