When I came to pick up Elizabeth, I was surprised to discover that not only had Matthew and Erika received stripes (confirming that Erika is indeed going to grading), Elizabeth got her first brown belt stripe as well!
Now it's just a waiting game to see if Maria is going to get her stripes too. Erika has been going to more classes, but since Erika couldn't go to class for a week or so they are still more or less at the same level.
