Nagini was terribly bored. They had been holed up in that old, crumbling mansion for days on end, with nothing to do, nothing to hunt, nobody to kill. At least, she told herself sullenly, opening her jaw wide to swallow her fifth mole of the evening, she wouldn't lack food here. The mansion was close to a copse, and neither her master nor his mousy assistant ever did anything to stop her going out, so she was free to roam and eat whenever she wasn't needed.
Shortly after swallowing the mole, she heard a rustling nearby. She moved to a clearing, where she saw a baby deer trying to get to its feet frenetically, even more at the sight of her. The deer's mother was nowhere in sight, and Nagini moved forward enthusiastically. The baby deer would make a fine dessert.
But then she stopped. Her master wouldn't be pleased if she ate too much. He'd already said she was growing fat. She'd better start watching her food intake.
She continued advancing towards the deer, amused at its struggles, but rather than biting it viciously, she curled around its legs, settling her head on her tail. After a few more attempts to get up and leave, the deer seemed to realize Nagini was no predator, and settled down, resting its head on Nagini's coils. Both animals closed their eyes for the night.
Nagini would reevaluate in the morning whether she was still hungry or not. Master didn't want her to grow fat, but he wouldn't want her to starve either, would he?
