Mansplaining has become one of the defining phenomena of the 21st century, and its pedantic tentacles touch everything from the last US presidential campaign to online riffs about how women just can't "get" Rick and Morty. While we've come a long way towards naming and shaming the mansplainers in our midst, on the flip side of that exchange, catching yourself in the act (and taking a step back) can be a challenge for anyone who's spent their whole life assuming that they always have something interesting and useful to say, despite all evidence to the contrary.
