Could anyone explain to me what the girl did? I understand that she testified, but what was the mother saying about her insisting on going to the store? I didn't understand the relevance.

In the video description it says she talks about "how she'll memorialize Floyd in her upcoming book ". Wtf? She's ten years old!
