She's 8! The point is that she handled the situation without getting upset or getting into trouble. Who cares if it doesn't quite match the question? Does it really matter?
That sounded kinda hostile. Perhaps there's a misunderstanding?
It's cool that she learned the phrase, but sasha was merely pointing out that she used it inappropriately. How else will she learn to use it appropriately if it's not pointed out to her when she doesnt (and when she does as well)? Also, you specifically posted in this folder (rather than the family and children folder, or cuteliness beyond belief folder) which is meant to showcase the use of this phrase.
That's totally fair game in the forum - especially since it's in the rules that if you cant handle people pointing contrary opinions out, then you shouldnt really be posting, and there's a thread in this very folder about using the phrase appropriately.
So all in all, your daughter is good for handling the situation without getting upset or getting into trouble, and sasha is good for pointing out an inappropriate use of the phrase. I am sure you'll get plenty more posts on both topics
