CHICAGO I remember reading about the concept of urban tribes several years ago, not thinking much of it beyond the fact that it was at least a dominant social group in prime-time television, if nowhere else. It wasn't until awhile later, when I moved 2,000 miles away from my nuclear family and roughly 1,000 miles from the nearest familiar face, that the idea really took shape for me.
Loosely defined (meaning this summary is straight from Wikipedia), urban tribes are "microgroups of people who share common interests in metropolitan areas. The members of these relatively small groups tend to have similar worldviews, dress styles and behavioral patterns. Their social interactions are largely informal and emotionally laden."
Now, if you're like me -- a young, single member of the LDS Church -- you'll have a ready-made foundation of a tribe waiting for you wherever you go, in the form of a singles' ward.
