I do not know… I see that sparkle in her eye…
Now, she is not spooky horse thats for sure. She is spooked or frightened after she has done something wrong, so it must be her past.
But in general I worked out last morning’s accident. She is just escape artist in some ways and as she feels much better, sparkles in her eyes grow…
After I put her back in pastures, I was watching her… As far as I dissapeared from her view, she started to hit the chain with hoof to get halter off again… Told her off and put additional rope around her neck, linked to chain so she is safe now for a while until she will work out this new additional lead.
She is a city girl, yes, she likes a crowd around her, then she feels ok, dogs and people working, tractors, car… as much as possible. And then everybody passing patting her, giving her treats, and kisses, and a looot of attention. I have two teens working in garden, and she just loves them around.
This will be busy summer, a lot of workers around, but in winter she will be bored. But no, she is not spooked by silly bird taking off stright between her front legs or something like that. Puika might be, but with her around… No, he is a big boy now 
Her stool improved instantly after she calmed down, it was just two loads loose, after she escaped and we got her back. So she is frighetend of humans, after she has done something bad. Poor girl, I hope we shall be able to bild her confidence back without spoiling her.
This morning my neighbour’s little bull was put out for the first day on chain on grass, and he was guite spooked by outside world too. He saw 2 our workers appearing on bikes, and run away. Got him, calmed him down and put back - he is such a sweetie, he wants cuddles all the way.
