It's a few weeks later, and things have gotten worse. Way worse. Turns out, her parents were totally right to be concerned. (Parents usually are, tho.)
But no worries! She's still "honest" (13.1), even though her master has "degraded himself to offer freedoms" (13.2).
She says that she wrote her parents news of these troubles some time ago, but the letter disappeared. Oops. She's worried that her master stole it, since he now seems to disapprove of the amount of time she spends writing, even though she's still tending his linens just fine.
She signs off by promising to tell them more soon, hoping to find her longer letter in the meantime.
