Baby needs a new pair of shoes

So Trudi got shod yesterday for the first time. The farrier trimmed her left front first, tackling the ugly quarter crack. He cut away the part that was splitting off from her foot, so now there's a hole near the bottom of her foot. He put on a shoe with clips and said he thinks it will grow out fine, and since it's on the outside we don't have to worry about her grabbing the shoe. She got progressively less enthusiastic about things as he moved on to the other feet. The farrier was really patient and nice, but I'm finding Trudi likes to be very good for a while, then gets distracted and runs out of patience. I think it's still young horse brain - she just seems immature to me- she has a "not quite grown up" aura about her, physically and mentally. It was her first time being shod, and he did hot shoe her (I don't know of anyone that cold shoes anymore, come to think of it). She didn't mind on the first hoof, but on the second there was more smoke and she was like "Why are you starting fires under me? Starting fires under someone is NOT COOL. I'm leaving."
She has a crack up the center of the other front hoof, but he said he actually rasped part of it away and the foot was fine other than that, so it's a superficial crack that shouldn't cause problems. With that foot shod he moved on to the hind legs. I've noticed that like most horses it's harder to get her to pick up her hind feet, and she did not enjoy having the farrier under there. She kept leaning to the side till she'd lose her balance, or move a front foot while a hind was in the air. I tried to explain that she really needed THREE legs to remain upright but she insisted otherwise and continually tested that theory. The farrier made various noises associated with exertion and occassionally pain but kept at it. We eventually moved against the wall where she could lean on something besides him. I distracted her by moving the leadrope around her face and she watched with interest. "Whoa....check out the colors....that's crazy, man...".
Third foot trimmed, and he moved on to the last one. We put her against the wall again and again she objected to having her hind leg worked on. "I'd smack her myself," said the farrier, interrupting my threats of violence against her (I usually don't smack a horse when someone else is underneath it), "but I don't think it would do any good." It's true- sometimes a horse gets more nervous and he needed her as quiet as possible- she is sensitive and I punish her when she needs it, but she can get a little jumpier afterward. He told me to play with her mouth to distract her some more, so I tickled her nose and wiggled her lips. Finished trimming, he put her foot up on the stand, and she kept pulling it off. "Trudi, you're killing me," he moaned, dragging it back up for the fourth time after she leaned/stretched/contorted herself away from the stand without moving her other feet. "Wow, she's really flexible!" I thought, impressed, but wisely kept this thought to myself. He finished rasping and at last we were done. Fortunately the hind feet didn't need shoes or we'd probably still be there. He said she actually has really good feet and that once the cracks grow out she should be fine barefoot with just regular trims.
Amazingly, he scheduled an appointment for next time.
