TPmav,
You're off to a good start for your second night out. You'll find that befriending the amog and approaching him is many times the way to go. The only thing I would suggest is once you get into a set like that where everyone is talking to you for the most part, STAY!
You need to focus on staying in set as long as possible, well until you are blown out really. You have to push your interactions. You need to get use to awkward moments of silence and other things get comfortable being in the group you just opened.
You'll find its very hard to be blown out and most of the time you can stay in set the whole night if you wanted to. People are very accepting of things.
Good job, keep up the good work man!
Jon
