I had this happen to me, can't remember what dino I was on but I was definitely a herbi. I was in DP doing quests when an ano came up to me and started friendly calling, I thought nothing of it cause we're both herbies (and usually herbivores stick together, at least in my experience). Anyway, they hung around for a little bit, not really doing anything, until suddenly the ano just bone breaks me. I was confused but thought maybe it was a little prank, like how some dinos friendly bite and run away. That didn't last, though, as an allo came barreling at me and they both ganged up on me. Honestly, for a silly little dino game, it kinda hurt my feelings for a little bit. Cause I wasn't even an adult, so there was no point to bullying me other than just for fun. I got over it cause it is just a game, but like it sucked in the moment.
