As to CelticClan and Bill, hate to say I probably dropped a few um's here and there, but I don't use the word like, like, very often, but, like, just once in a while.
It was pretty much up to me last night, so I treated it like a more casual version of the MOC interview. My BGO was nothing like I had expected; I had pictured a man in his late 30's to mid 40's, but found him instead to be sort of a grandfatherly figure. Very friendly, told a good number of stories during the interview, and really made it feel like a conversation rather than just asking questions.
He spent about an hour with my parents, and then another 1.5 hours with me, and then about half an hour more talking to my parents again. I think it went well; just hoping to see a favorable outcome.
A question for those of you who have been through these things before:
Do BGO's ever extend the interview to a second time? The impression I got from mine was that he wasn't going to submit his report until he had talked with me again, given me some materials to read, etc. Part of the reason being that I had never been sent a catalog from the Academy, about which there are required questions for the interview.
