I've told four people - well, three, and one sort of guessed this morning
I was talking with her (she's the one that wrote the story with the unicorn and made me think of MLP)
Le Me: "Don't be too disturbed by this... I read 'unicorn' in your story and instantly thought, "MY LITTLE PONY!""
Le Her: "Rofl"
Le Her again: "You're not one of those guys who's obsessed with it are you?"
Le Me: "Define obsessed."
The other three were the brony friend I have, James, who I have told you about.
The two left are my best friends. One is indifferent, the other is almost interested. They are siblings, the older is interested, the younger is indifferent.
