I am 47 years old. I have two post-graduate degrees in mathematics. I have ridden over 250 different roller coasters. And it was only this past Friday that I tumbled on to how Nightmare, the Ghost Horse and friend to Casper the Friendly Ghost, is female. And not by deductive methods such as, like, reading her name. I had to have it explained to me by the Casper the Friendly Ghost wiki. So, you know, I’m a deep thinker. And somehow, even though Harvey Comics were pretty good about having a important female characters, supporting and lead, I thought, “well, this horse doesn’t have a bow in her hair and long eyelashes and a skirt, must be a boy!” and stopped there for four decades.
