I doubt any of you all are very concerned about this

, but I have an update. I'm making headway, folks! After trying unsuccessfully to reach my ex-friend by cell phone, I called one of our mutual friends. He finally got back to me and said that he didn't know her parents' address or phone number, but that he wouldn't mind to call her ex-boyfriend for me because he just went up to visit her not long ago so he would know. So...I'll let you know what happens.
