Of course, this example is just one type of the glorious and varied world that is nerdsplaining. Perhaps my little diatribe is fated to become the first in a series of posts about this pernicious behavior. I’m sure most of you have run into it at one time or another (or, depending on your friends, over and over again). What’s your favorite nerdsplaining story?
