Which detail from "tenth day: tenth story" in the decameron best demonstrates griselda's stoically patient attitude?

I read the summary of the story. Griselda demonstrated her stoically patient attitude all throughout the story.

She allowed herself to be humiliated in front of many people when Gualtieri asked her to strip naked. This is to show her obedience to her husband.

Despite the many sufferings Gualtieri subjected her to like belittling her, taking away her children and letting her think they are dead, she did not go against his wishes nor did she get enraged.

She even allowed Gualtieri to divorce her and let her serve the next bride. She treated the girl well and did not show any negative feelings towards her. This ultimately led to Gualtieri's realization that Griselda is very patient and that he chose well when he chose her for his wife.
