Curiosity will scare the horse.

So today my dad needed to get into the paddock with his back-hoe and refill an area with gravel. When it rains alot and hard all the dirt near the water and side of the barn floods and runs down the slight hill and make a mess. The horses are fine walking on it to get to the water. So I open the gateand there are Cook and Jaz standing there, wellnot for long once Jasmine sees the tracter she is out of there not like flips out and runs away more like turn around and trot off. Cookie just stands there looking at it while it passes by. We've done this before and Cookie always walks up to it running or not and investigates. Her favorite thing to do is walk up to it and once it moves wait until its right next to her an run off like a scared little girl. I don't think she'd ever notice if it ran her over. And when my dad is digging she'll stay a distance away and eventually creeps up to it and gets like within a foot of it, and once it moves turn around and trot off. She is a silly, curious girl. So glad it doesn't bother her. Jasmine in ok but she takes the saying "Scared shitless" literally, for really anything that startles her to a point, she tenses up and...ploop. I guess she was scared shitless. xD
