For some reason, Vanilla Bean doesn't like Ann and me showing affection for each other. I think it's mostly jealousy - she thinks Mommy is all hers and doesn't like us holding hands or even necessarily talking to each other. We mostly deal with it by trying to ignore the screaming and protestations.
Last night, Vanilla Bean and the Monkey were in the tub. Ann and I were standing there, so I reached over and gave her a hug. Vanilla Bean looked up and very seriously said, "Stop doing that! Stop being so married!" We busted up laughing, and fortunately she realized she'd said something funny and laughed with us.
