In hindsight, this is what I think happened. Dante was sore. He has a long back and a lean build. At five, he’s physically immature. He is growing quickly and his saddle had become tight on his shoulders in the three months since it had last been adjusted.
His soreness corresponded to me injuring my knee (not horse-related). As we were both developing our soreness issues, I made a couple of mistakes. I can see them as mistakes in hindsight, but at the time didn’t realise I was doing the wrong thing. In fact, I thought I was doing the right thing.
