Humans are persistance predators.
Beyond the obvious alarming consequences of this, it also causes them to be prone to holding "grudges" against those they feel have slighted them.
A most unexpected consequence of this, in turn, is their habit of becoming competative against inanimate objects.
In the event you find your human fighting with or declaring war against an object (can opener, computer programme, keys, jar, so on) or referring to a struggle with it as "personal now" do not be alarmed. The human has not lost what little sanity their species posess.
