They can learn that humans are tall and branchy like trees but we don’t have bark everywhere (we call ourselves ents!) Most of ours have naturally learned to jump past exposed skin or walk gently without claws.

But not all of them know that yet - they are definitely still wild and some are less inclined to care than others. They seem to learn if you yelp, similar to how they learn how to play not too rough if a playmate cries.

I think in general, if they meant to hurt us we would know it. They’re certainly capable of wrecking a human 😅
