When I was in, it always bothered me that I couldn't remember much about the "spiritual" food we received and I frankly never once went back over the useless notes I took (snooze fest!). I could tell you in detail what my friends wore, what we talked about, etc. I felt like I must not be spiritual enough and would beat myself up over that feeling, but I would definitely parrot the overused line "best convention ever."
So glad I am not shackled to that silliness anymore.
