Hello and congratulations on turning 21! I totally recognise your situation. I had a very limited selection of friends (more like a handful a acquaintances really) and then I started to gather some from disparate circles. I have found, after several trial-and-error situations, that mixing friends from totally different circles often makes for an excellent party. Really. People who in all likelihood would never have meet each other have a lot of questions to ask each other and lacking questions to ask talk, talk, talk (because some people are better talker than listeners – just can’t shut up but are still entertaining). Putting people in an unfamiliar situation often creates a bit of nerves in the beginning, this often (in my experience) translates to chatty people and interesting conversations (and more drinking) leading to more interesting situations that in turn build the base of a really good party. When meeting a bunch of people you never have met, and never would meet otherwise, you’re bound to find someone of interest to you, and vice versa. Which can not be said for someone’s umpteenth dinner with friends from work. I’ve been to parties mixing everything from pot-growers (legal of course) and old (70+) representative of ancient European noble houses. No one was really in their element in the beginning but all agreed in the end that it was an interesting party. Interesting is good and most people go to the same kind of events all of the time. If you can be the one to mix it up you become the link between worlds (tacky I know, but you get the meaning). My parents always said that I was special and my friends called me odd. Same thing, different perspective.
