But that would be to assume that social skills and social/public behavior is synonymous with personality. I’m not sure it is. The dictionary says personality is the combination of qualities that form a person’s character. And character is defined as the mental and moral qualities unique to each of us.
I was also the weird kid with a mop of hair and hand me downs. Like you, I learned how to “fit in” but I honestly never felt that I changed my personality. I only put on a different public face. Inside, I was always the same person.
Perspective, I suppose, but maybe the way you changed wasn’t “faking it” so much as adapting? Kids do that really well. If adults could adapt like kids do, the world would be a nicer place, I think.
