A random marriage incident I heard about last week-- a couple of friends of mine at church had a commitment service a few years ago (we Episcopalians aren't doing proper weddings for same sex couples yet). One of their guests, an elderly widow, recently used the same commitment service recently with her boyfriend. They didn't want to get legally married for a variety of reasons, but they didn't feel comfortable "shacking up" without some kind of religious sanction. Pretty cool!
