Something that caught me: she seems sour about moving forwards. Her ears were back and she had a sour expression on her face when she was trotting. She was also trotting in a very strung out manner. She was very quick to stop. This isn't a bad thing, but I couldn't see them asking
for a trot/halt transition. It struck me more as them asking for a trot to walk, but her giving them a trot to halt. She might be the kind who just decides, "I'm done with work! Screw you!" She strikes me as a little bratty about being asked to move out and work.
More experienced people can now say educated stuff. I'll go get my coat.
