I've learned that anybody and everybody in the world can access every single tidbit of my personal information at any time down to the hospital room number I was born in. I've become noticeably more cynical. I've realized that nobody pays any more attention to my thoughts on this board than I pay to theirs. I've learned to live my life in complete inhibition, to avoid unfair judgments against me.
I'm honestly not sure if it's this forum, or high school, that's affected me in this way.
