Hey! They're talking about me!
Exactly as noted, I don't really mind social interaction per se, and actually quite enjoy it in small doses. I just find it to be exhausting - as if I'm surrounded by spiritual vampires who just want to feed on my carefully husbanded energy (which to some degree is exactly what I think it really is, but that's fodder for another post).
I much MUCH prefer being entirely solitary, and especially in the middle of the night, when it's just me and the moon and the stars and the owls and the crickets and the whip-poor-wills.
