@alice I also like to explain things I feel excited to know to other men, including my boyfriend, who vary in degrees of "already know this to an expert degree" to "can't possibly understand, but thanks for being so excited about it"
I'd post a blog instead of outright telling people to their faces, but invariably some actual expert would wander in to explain to me all the ways I got it wrong.
Better to just shut up and assume everyone else just already knows everything they ever want to know and hate things being repeated to them.
You know, the exact opposite of myself, someone who loves seeing things explained and can't get enough of people dumping on me.
