Hermione sighed with relief as she took Ron's hand and gave it a gentle squeeze. He had wisely cut off the avalanche of candy and biscuits after dinner, and she'd played enough that she would sleep well and deeply through most of the night. "Thank goodness. That's one of the problems of being an only child - I keep forgetting how energetic young children are. I feel so old!"
Crookshanks trilled up at her, then slowly eased himself through the not-quite-latched door to Leila's room. He fluffed his tail as he trotted up to the bed, paused, and leaped up onto the foot of the bed. He sat, gave Hermione a "what did you think I was going to do?" look, then settled down to nest against the little girl's feet.
Hermione crooked a finger at the door, which obediently shut itself with a faint click. "Well. I think she has her own guardian kitty tonight. If nothing else, he'll make sure she sleeps through the night while we - exchange presents?"
She smiled up at Ron, head cocked slightly to the side. Leila was in bed, it was Christmas Eve, there was a fire glowing on the hearth - what could be better than this?
