Everyday after school, from 8PM-9PM, I go to a local place to take cuban salsa lessons. So I go there, and I basically know all the young people there(85%+ = old people lol) but it's still fun. However as of late, everyone my age has moved on in level and has started attending from 9PM-10PM, so I get there and sit around in a bored mood all hour. Now I've noticed there is a HB9 that comes in nearing the end of class, and there are little-to-no opportunities to talk to her. If any arise, they aren't ideal at all(super-loud music).

So basically, my problem is, since I come in and I don't talk to anyone for 45 minutes putting me at 0 enthusiasm level and 0 social mood, I have trouble talking to the HBs that come in near the end of class. What can I do about this? How could I put myself in a social mood?

Any general tips on this situation appreciated.
