When you mention "I could be wrong" as being the major load bearing part of the response to a hangry person—especially out of a sense of maintaining emotional stability—demonstrates that epistemic charity and humility is not only an intellectual virtue, but also an emotional and empathic one as well. I find that this would be the trickiest part: the balance between making one feel heard while also providing useful feedback to what might actually help them—trying to find the middle between appeasement and callous criticism.
