My oldest and her partner are talking commitment ceremony at some point in the next year or so. (They're not living in a state where marriage is legal yet.) We'll be there celebrating with them when they do.
BTW, TrueMajority's doing an e-petition in support of marriage equality that I'd like encourage folks to sign. It's at http://www.truemajority.org/Equality . I truly don't know how much good it will do, but it's One More Thing, and, what the hell? 30 years ago, I don't think we could've truly foreseen this in the US and now it's happening.
