As we were standing around in the parking lot last night doing this, it occurred to me that this was one thing that was never mentioned at all in my original training: Debriefing the dive. This means not just, "Wow, was that ever a huge octopus?", but talking about what went well, what worked and what didn't, how everybody's skills looked, and so on. It can be as simple as, "Where you were, you were a little behind me, and kind of hard to see". If you are going to dive with the same buddies over and over again, it seems like this kind of thing would be very useful. Obviously, it might not go over well with a random instabuddy . . . 
How many of you do this?
