I rode her before the lesson with Kristen, Miranda and Megan. We had some time to ourselves and she was doing rather nicely. Then Miranda came in and was lunging Tag (at my suggestion), and he was being quite the pill and some of that energy rubbed off on Elsa. She was not naughty, but she was frazzled a bit by it. Kristen was riding Sif and they were being quite, but it was another mare in her space and she was a little worried about that.
We worked through it and she produced some good work despite the circus, which was excellent.
