This makes sense, but you obviously still understand why she doesn't need a reason.I understand that and respect that. The thing is, we have for the last two years, been very tolerant of each other. This was so sudden and hostile. One of her horses has made it to my hard before. We just brought him back and called her at work to let her know we took care of it and she might want to secure her gate in case it happens when no one is around to catch it. We didn’t want him wandering to the street. But yes you are right. It’s her property.
Heres an example, the horse showed up once. Our horses escape from time to time. Not anymore, but every now and then when we were new to the fencing thing. We have good neighbors would would hold onto them knowing we would show up right behind them.

If her horse was showing up a couple times a week, you would get frustrated. Horses have big hooves that do a good job at treating up a nice lush yard.
You don't mind returning the horse if he comes once, but after a bit it would get old. Maybe you'd think it was nice seeing him every now and then for a little while, but after your yard starts to get torn up, you would change your mind.
Of course, difference situation with a much heavier animal, but you know what I mean.
