Why are teens picky about friends?

Teenagers do not have a fully developed psyche. It is just being formed for them. Teenagers are very dependent on the opinion of society, it is important for them to appear better than others. They strive to create their image in such a way that their peers will respect them. In view of this, the choice of the environment also occurs under the influence of society. Teenagers are drawn more to people who are active and popular, and to those who seem withdrawn and downtrodden, they experience vague feelings. They could be friends with such, but only their reputation will suffer, so guys rarely choose such a friendship.
