Young horse-crazy girls form amazing connections with their horse-friends and they’re loved back.  But horses have freaky little anxious pea-brains; you never know what they’ll consider threatening and when exactly they’ll need to drop what they were doing and tear off at an equine warp 9.  God have mercy if you happen to be wrapped up in their massive death-pistons right then.  This is almost as stupid as lying down on or near a horse that’s lying down.  They have the mentality of a slightly daft great dane but weigh over 1,000 pounds and are terrified of everything.  Very few will hurt you on purpose, but it happens all too easily by accident.
