Rob: If you still read this, tell your girlfriend that yesterday was the last day of the session, and she can collect the ribbon and certificate at the front desk next time she's in, if she didn't already know. You can also tell her that her daughter passed the level, and that she'll be learning side-breathing next.
If you were worried that I would fuck her over, I hope now you know that your fears were unfounded, and that I would never punish a child for any grudges allegedly held.
