I'm starting to see where that stereotype about "autistics can't lie" came from. Hello, they can lie just like anyone else, but they often lack the ability to manipulate people with them. Most of Rose's lies are very well constructed... just not the Rhyhorn one. She'll wait until parents are out of the room and, during a disagreement, she will make up stuff that didn't happen. Woodjie is not that clever socially and if you ask him, "Did you hit your sister?" he'll tell you. Poor guy is genuinely upset that Rose is saying that he hit her, when SHE just hit HIM.
Thankfully, Dad is on the case. But when she is in trouble, Rose has taken to saying, "I not wuff youu," and folding her arms or hiding her head. Sometimes she will even refuse hugs when the banishment to the chair is over.
