According to the Google search I just conducted, others have wondered the same thing.
It's the kind of thing you've gotta consider if you know anything about EB's story. She left behind almost no written record of her short life -- no letters, no diaries -- beyond Wuthering Heights and some juvenilia I believe exists but have only read about second-hand. Luckily, Charlotte loved her and wrote about her -- often a bit disingenuously, but that is what an older sister does when she wants the world to remember her younger sibling as more angel than oddball -- or even worse, social deviant. Because Emily Bronte was no Victorian "Angel in The House," that much I know is true.
I mean, have you READ Wuthering Heights? Heathcliff is no romantic hero, whatever the back of your Signet Classic says, and Cathy is as cruel and dangerous as her soul-mate.
Ugh. Shades of Scarlet and Rhett?
Oh, geez. Really??
The first time I read WH I was a teenager, and all I could do was hug my knees and wonder how so young a woman could have imagined and written down such heartbreaking acts of violence and cruelty. This was the stuff of nightmares, not of love.
None of this answers the Aspie question, but all of it is interesting, as far as I'm concerned.
And that, Readers, is your non-sequitur for tonight.
Once again, The Striped Nickel delivers. FTW!!
