i dont really feel like its "withdrawing" or being closed, or even that it is odd. i think some people have a strong preference to spend a lot of time by themselves, or at least only interacting with a few people here and there. or with people they naturally have a kinship with...
i really only go out to the kind of things that i enjoy doing, and its rare. usually i like to just spend time with only the few really close friends i have, or spend time talking with them, writing to them or whatever. but there are some things i like doing, with people that i really connect with, and truthfully that is also rare for me. we do have a nice community here, and some cool places and opportunities for people to connect in different kinds of environments, so in that way i get to meet a lot of people. theres a nice weekly farmers market here, and its definitely a big part of our community/social life here, its very well attended.
if you found some kinds of things like that, that you were into...eg a class on something, or whatever other social place that people network not around partying, drinking...the chances of meeting more compatible people seems better.
but none of this seems to me like it odd, or should be a different way.
i think when you meet the right people, and have opportunities to do things that you are into , then its all easy and it all just flows cause your on a similar kind of wave...
and you dont really need to trip out on trying to be more social or open. unless you feel drawn to do that, in which case you should just go for it =)
sometimes i do have to make myself get out and about...just start out walking and then i meet people and things happen.
in a lot of communities theres a lack of places and things to do that dont revolve around drinking and/or other weirdness. truly a lot of what people do perplexes me, i cant see myself being interested in watching sports, or going out drinking all the time.
i do like drum circles, the occasional party/rave/music performance. but mostly just small groups, or one of one interaction with people. going to the beach, the river, or the mountains and wandering around and hanging out, thats mostly what i do when i hang out with my friends.
but everywhere theres cool people to meet who are doing different things, and creating spaces and places for people to come together in different ways.
or just socializing with the people around you, as they are, whoever they are....that has its way too...
