@Lash,
The bay area is sooooo big. I never did live there, but have still have some friends and acquaintances who do - but those became friends over a long span of time - several of them people I'd met in Los Angeles years before. The area is rich with different neighborhoods and the diversity of the population, but hard to get to know all at once, for sure.
Hard for me to advise since I'm not very involved in my new city either, though it is becoming more "mine" in my mind as time passes. But in my last new city, when I was more upbeat and outgoing than my present self, I walked more, getting to know some neighbors, and went to some events involving people I met through our gallery/studio, and could call some of our artists my friends, as they became so.
Off the wall advice - see if there is anything you might be interested in that doesn't involve La Famiglia or, much as you like it, teaching.
On getting used to a place, Diane and I were talking recently about trees in different places, and how we feel about them, and I told her about my experience with the Sequoias (redwoods) that enclose miles of highway between SF and Eureka/Arcata, and beyond. The first several times I drove through the forest, something like 160 miles, I thought it was beautiful in many ways, but somewhat alien to me (raised in a semi arid desert, no matter how planted up some parts of it were). I'd no strong emotion to them, nor against them, but more self comfortableness going on when the ocean showed up at the end of the trip.
By the second or third year there, I started putting on symphony and opera cds as I drove through the forest, occasionally nice and loud, reverting to blues and rock when I got into, say Sonoma County, when going south. Last time I drove through, some tears fell because of my emotional connection to the forest.
This all started when she mentioned the incredible beauty of the fall color in the east. Even though I've lived in the midwest and eastern US as a child, it wasn't for all that long, and beautiful as all that fall color is, it's not mine (yet).
Attachment is a funny thing. It can creep up on you..
