Opossum stares at you as if they are tired at the mere thought of having to interact with you. After a while of staring at you in silence, they give you something from their private stash.
Opossum greets you cordially, but the tone and their body language show that they don't really care to hear an answer. Or anything at all, really.
Opossum looks bothered by something, but when you ask them what's wrong they just grumble and refuse to answer.
