Seattle has an active alternative living scene and there are a wide variety of cooperative living arrangements available - so, if you want to live WITH people, you can probably find a place and group that works for you. Options include non-profit corporations that own and run co-op houses, cohousing (cooperative groups of private homes with common facilities), group houses (friends who live together, share some meals, and consider themselves as almost family), and shared-income communes. There are other kinds of intentional familiy and intentional community available for you to share.
