Because I don't speak horse so well and Grace has a quirk I don't understand.

It's slightly hard to explain so bear with me! Some important things to outline:-
Grace is:

- Used to being led around on her own
- Happy to lead behind or in front of another horse and can cope with them disappearing
- Generally quite brave. She might look or spook at something the first time, but not habitually
- Beta, she will defer to other horses and is freaked out by some people, usually men

Yesterday there was only one other horse out with Grace. We brought them in together. On the way back to the stable Grace exhibited behaviour I have not seen before. Much spooking, bug eyed, bouncing and double barrel kicking out. It didn't matter where the other horse (a friend) was - behind, in front or alongside.

Now I know there have been trespassers in their field and I know how some people really do alarm her. Mostly men but not always. There were people in the field yesterday and today. The only thing I can think of is that either the stranger danger or maybe a fear of something coming up behind freaked her out.

Anyway, as I said, I don't speak horse that well so I can only speculate and hope that she is never that afraid again. I also hope that the trespassers get more sense because one day one of them might get hurt. (I mean really - tobogganing into the middle of a group of horses - what were they thinking?)
