Marry a Girl?

Last night Bella declares, "I wish I could marry a girl." I quickly remembered all the wise counsel I've received in the last five years, and instead of going in to panick or damage control mode, I simply asked, "Really? why?" She tells me that if she could marry a girl, she'd marry Arianna so they could always live together! Awww...how sweet (and not at all where I thought that conversation might be going)!
