Same. I was sheltered but I was very outspoken as a teen. Didn't let ppl talk down to me. (Unless they looked like they could beat my butt, LOL otherwise, I don't back down) Nowadays, I work around a lot of adults/elderly ppl that likes to think everyone younger than them is beneath them. I just look them straight in the eye when I'm not having none of their sh!t. Politely and seriously.
30 is a weird age. Not quite "young" but not "old" either. If I dressed "like my age" I'm afraid to look like I'm trying too hard but if I dress like a teen/20s then I look even younger.
And I love sweaters because I'm always cold. My body temp. runs colder than an average person. Even in the summer time.
