Over the weekend, I learned from her mom that she did very poorly in one of her classes. Her mom stressed to her that it should not be a big deal, and asked me to assure her the same thing.
I had been trying to find a private time to talk to her about it. During the lunch hour today, I calmly told her what I had learned over the weekend and assured her that it should not be big deal, and not to blame herself for it. I really meant it. I know that this must have already caused herself a lot of stress last semester.
