Session didn't go like I wanted it to

My friend and I had a playday a couple days ago and since then I've been thinking about it. It was not a great session, for most of it Marsan was not connected or even thinking about my requests. BUT, this time I didn't make it more than it was and is, I accepted that it didn't go like I wanted it to and learned as much as I could. That's because I saw it as playing, and when your playing with a friend you don't really worry about whether it goes perfect or not. Before I've felt like it is work to go down and do stuff with the horses, when I think about it that way, then it feels like the horse is getting in the way of your "work" when he doesn't do what you want. I have made a big improvement in that I didn't really feel that frustrated, I just knew with certainty that there are good and bad sessions and they both help you to learn.
