Today my horse took off with someone?

[Ruckus]

It's not your horse's fault. she wasn't naughty. she was being a scared horse.
when you're scared is it your fault? no.

When this FB leaned forward I BET ANYTHING THAT HIS LEGS WENT BACK AND HE PRESSED ON THE HORSE'S SENSITIVE FLANK AREA and that's why your horse bolted.

Or he SQUEEZED his legs without thinking.

Clearly, this horse is too sensitive for this total beginner FB who should be sitting on a babysitter type of horse, not a sensitive horse.

So, how to stop that from happening?
Don't loan your horse to anyone who isn't experienced enough in riding.

Some horses shouldn't and can't be ridden by just anybody.
they are a one person type of horse or an experienced rider type of horse.
that is your horse.
