I look like I'm straight out of school, sometimes people explain things to me like I know nothing.
Not that I think they're automatically malicious. Sometimes I find myself in the "explaining" position because I think not explaining makes me sound I'm cooped in an ivory tower.
My birthday is September 10. September 11 2001 happened. While I'm not directly affected, it messed me up mentally because I thought I had something to do with it. It didn't help that the year after, I saw Space Shuttle Columbia on the launch pad in what would be its final mission.
