I have, and not even in a good way for the most part. As a child I was much more outgoing. I was still an introvert at heart, but I could actually speak up, go up and talk to people willingly. Teach, look how at how great my handwriting is! Teach, my pen pal and I have so much in common! Hey you, want this magic wand I made out of a straw and a sticker gem! It's hard to even start a conversation with my family nowadays because of my shyness.
I was also more feisty and assertive too, which I'm not sure is a good thing or a bad thing. Like I got into a fight with a neighbor in 4th grade, stood up to my mother more, and had a phase where I corrected everyone's grammar on the internet. Over time I became more chilled out, which is a good thing I'd say.
I also feel dumber then my younger self. I went from being labeled the smartest in my class to making typos constantly and being awkward in conversation because I can't come up with a reply. Also younger me was doing crafts, making OCs, drawing more and making her own jewelry. I've always liked those things, but over time I just lost the inspiration unfortunately. I'm working more on my art though these days though. Lol, why did I become such a disaster?
