Probably Experiencing Auditory Hallucinations?

"Brother Ko, I genuinely wish to help you, but I'm just a leader elected by the shelter and can't make decisions arbitrarily. I have to consider everyone in the entire shelter."

It wouldn't sit well with my conscience to watch you suffer without help. After all, I'm actually a very good person. Besides, we're good brothers. Since you've personally come to seek my help, I can only set aside some of my rations for you. I just hope that the zombie horde has retreated. If they're still outside, we might end up starving like you!"
