Story number seven from the Lunar Tales.

For seven months, Blue Moon has been carrying hers and Night Watch's foal, but was still working despite that fact.
Night Watch tried everything to make her wife taking a break, but without success.
After weeks of worrying the doctors finally required Blue Moon to rest at home, forbidding her from any work.
What happens if both mares are at home, and neither is able to do their work for the day?
