It's not accurate to say that everybody has a weird personality in their childhood and then suddenly changes into someone different as they grow older. People's personalities are shaped by a combination of genetic factors, life experiences, cultural influences, and individual differences.
During childhood, individuals are still developing and learning about the world around them. Children often have vivid imaginations, boundless curiosity, and a sense of wonder, which can sometimes be perceived as "weird" or unusual by adults. However, these traits are essential for healthy cognitive and emotional development.
As people grow older, their personalities can evolve and change based on their experiences, education, social interactions, and personal growth. Some aspects of a person's core personality might remain relatively stable throughout life, while other characteristics might shift or adapt in response to different circumstances.
It's essential to recognize that "weirdness" is a subjective and relative term. What may seem unusual or eccentric to one person might be completely normal to another. Embracing individuality and uniqueness is an essential aspect of human diversity, and it's natural for people to have different personalities and quirks throughout their lives.
Ultimately, the concept of personality development is complex and multi-faceted, and there is no one-size-fits-all trajectory for how a person's personality evolves over time. People are wonderfully diverse, and our personalities continue to be influenced and shaped throughout our lives.
