For the Tang Army soldiers, letters from home are quite a common thing. If they do not have tasks, they have the chance to write letters home twice a week. You can use any free time to write, and once you finish, you wait for the postmen to arrive.
But for the Allied Forces soldiers, whose transportation capacity isn't so abundant, the opportunity to write home becomes extremely precious. They usually can write a letter home only once a month, and these letters often end up being "lost."
Yes, lost! When the military faces transportation shortages, it's easy to lose letters that aren't deemed so important. Everyone does it, so not many people pay attention to these things.
Aunt Curley has been quite absent-minded these past couple of days. She still has no way of knowing if her child is alive, and the occupation of Hotwind Port by the Tang Army has left her feeling somewhat idle.
