You win some, you lose some. Today I compromised with Lucy and had to tell myself it was better than conceding. She had it in her brain that when we circled at the far end of the arena, we needed to actually change direction. We'd come out of the turn and she'd switch to the right lead and try to muscle me across the diagonal, instead of completing the circle to the left. Eventually I just booted her with my right leg and growled at her, but she didn't want to switch back to the left lead, so we had to go back down to the trot and then start again. It was kind of an exhausting ride.
