What The, Huh?

In a bizarre and truly odd development, Bill's sister (to whom I've spoken on the phone once, maybe twice) added me as a friend on facebook. Huh?

Couldn't have anything to do with me spending the night at his parent's house the last night we were in Indiana (it just made more sense, and we're logical people). I'm pretty sure that his parents got more convinced than they previously were that we're dating.
