Not necessarily knightrider. But I have to feel like it's a horse I COULD fall in love with in time. It's more about demeanor that looks for me. I like a horse to be interested in me, to want to interact, but not too aggressively. I want it to be happy to move forward, but not so much energy that it's no fun for me. What I'm searching for is a horse with the right balance of liveliness and level-headedness. But it must also not have any big red flags. I don't trust myself enough to ignore those just because my "gut" tells me it's a good horse deep down. I think I would recognize a horse with potential though, even if it's not perfect right off the bat. So far, none of the horses I've tried made me want to bring them home, even though they all had nice personalities. I think the 18 year old mare would make a fine horse, but she needs retraining and it just doesn't make sense to do that for a horse that I might only ride for a few years.
I think I need to feel good about bringing a horse home. I need to feel confident that I can handle whatever it throws at me and that it will be pleasant to have around. Beyond that, I think I could grow to love any horse.
