After traveling for a while, I reached a patch of trees in the middle of a sea of grass. The patch of trees was big enough to be considered a small forest. I decided to rest there for a moment, so I directed the horse to stop there.
"Woah there. Stop right here."
The horse stopped and I got off its back.
"If you try to run away, just be warned that I'm faster than you. The only reason I need you right now is because of convenience. But just in case..."
I tied the horse to a tree. Once again, Grandpa's camping survival lessons were useful. I pulled on the ropes to make sure the knots were knotted well and wouldn't let the horse escape when I'm not looking. But even if I wasn't looking, my Wind Sense will still pick up her movements, alerting me, not that the horse knew that.
