I can't help it. Chest thumping is a genetically ingrained dominance display behavior in my species. If that doesn't work sometimes I'll throw sticks or fling poo.
I have a soft side too. If your my friend I'll let you consume my cooties.
I do not fear the Birds of Prey. All they do is cherry pick defenseless little furry critters and when they see their reflections in a mirror they think they have found a wingman.
