Childlike Self-Concept 

This is the term for an adult or adolescent who sees themselves as a child. People who feel this way are very misunderstood because when you attempt to explain this condition, people don’t take you seriously and think you are just being dramatic. People who feel this way tend to be on the Autism spectrum or have trauma, such as abuse.

Anthony: Our neighbor Calvin is a weirdo. Why is a grown ass man acting like a little kid and playing with little kids?
Tonya: I think he has a childlike self-concept. Even if we don’t feel this way, we should love and understand people who are like this
