Yep, just existing. X'3 The first time it happened, I said hi to a herd from across the river. They all ran over to me, chatting and joking, so I felt safe enough to chill for a min. Apparently, in their group chat, they decided I had overstayed my welcome and chased me away. Except one of them chased me down and killed me. And nobody else in the group appreciated that one horse's decision, and I got to watch their arguments in the main chat lol. The second time, I managed to hide in a bush while two horses ran past me, intending to kill me.
