My wife has accused me of mansplaining when I really was just sharing the information I had in my head about "the thing" because I was proud of myself about that.
There's also the "You may already know all this, but it's worth saying out loud anyway."
I'm not saying mansplaining isn't a thing - it certainly is - but there are other innocent "info dump" kinds of things that can look like mansplaining but weren't intended to be. I try to be very clear about why I am info dumping when I do, but I'm not always able to catch myself in time.
