Fais pas chier!
I was a horse mad 12 year old - I had responsible parents. The future generation of equestrianism does not depend of lax parenting, IMO.
Nor on a harassed woman who wishes to enjoy her horses at the end of the day. The child is harassing the OP and if it were an adult, I'm sure lots of people would be outraged and horrified for her and tell her to call the police for advice!
