Our holiday food splurge was a small crate of tangerines, which we found ridiculously thrilling after an eight-month abstinence from citrus.... Lily hugged each one to her chest before undressing it as gently as a doll. Watching her do that as she sat cross-legged on the floor one morning in pink pajamas, with bliss lighting her cheeks, I thought: Lucky is the world, to receive this grateful child. Value is not made of money, but a tender balance of expectation and longing.
