I have always had trouble retaining certain "common knowledge" type facts despite doing well in school generally. My friends used to (gently) rib me or stereotype me as ditzy for it. It literally never occurred to me until recently that my trauma (and undiagnosed but all kinds of ADHD symptoms too) could be the cause for that either. Part of me feels too old to try to "fix" it now. I don't really want to be medicated. But yeah, relate to this a lot lol.
