In my latest trilogy The Horseshoe Trilogy a Romany lady called Nellie tells Joe that horses mirror our feelings. I often notice this when I’m with our horses. My niece Sophie was staying with us a couple of years ago. She got on very well with our Exmoor pony Gaia, who was then about one and a half years old. While she was playing with her in the barn one day I took these photos. It was only afterwards, when I looked at them closely, that I realised Gaia was mirroring Sophie’s expressions and body language. Fascinating!
