I have always been an introvert. This doesn’t mean that I avoid people or totally hate social gatherings work. I still had/ have friends. An introvert tends to have few close friends. Those friendships are “deep and close”. They find one or two people to interact with at a party. They tend to take a few seconds before jumping into a conversation and perhaps sees another angle on a situation. An introvert needs some time alone to be healthy. They get their “energy” within themselves.
Extroverts are different. They interact with more people in a social setting. They tend may have more friends / social contexts but have fewer “deeper” friendships. They tend to speak up faster , often interrupting someone else and tend to speak without fully thinking things through. It’s hard for me to describe an extrovert because it is so different from who I am. They get their energy from other people and tend to not like being alone.
I became more of an introvert after I got hurt. My comfort zone is much more narrow: including things like new settings too many people. I don’t do well with changes. My comfort zone is what I know. New things set me into anxiety. Being alone, having control over my surroundings, knowing the people around me- it’s no longer a true preference, it’s survival.
At least it’s not something different for me.
