Entering a new social scene, whether dance or work or otherwise, is always rough and requires either waiting around until you're known or just introducing yourself and making friends. That's the way it is. Of course, if I was willing to settle for that and take the easy way out, I wouldn't have bothered writing about it for the last few weeks. It's easy to be lazy and just ignore the newcomer and put on them the burden of meeting everyone else. It's a lot harder to overcome the trepidation of trying to break into a existing social circle and to ask a better dancer for three minutes on the dance floor.
Some people have a really hard time with it.
Even advanced dancers have a lot to learn and need to spend time doing it on good dance floors because not everyone owns a studio. This is a very good point. If you go to a practice with an strict agenda, it's frustrating when you get thrown off the plan. If you're practicing, for example, for a competition, you need to concentrate on your game plan. My point is that it would be pretty nice if the more experienced dancers could take a few minutes out of their routine to welcome the newbies so they don't feel like intruders.
