DD13 hates to not be aware of the complete context and background of any and all conversation around her.
Oh lord yes! DD is just like this. I also have to explain all the New Yorker cartoons that she doesn't get. (Some of them really don't translate well for the 8yo brain.)
A quirk I've mentioned before is her ability to see letters and numbers and then county and state shapes in sticks, leaves, toast, shadows, etc. We were playing Pictionary the other day and I literally drew the beginning of the top of the state of Idaho and she shrieked "Idaho!" When she was 2 she had most of the countries and flags of the world memorized from a poster she had on her wall. I was such a clueless first-time parent that I had no idea how unusual this was. I really should have taken a video.
