'I need the most firewood due to a congenital issue that results in us having poor blood circulation to our extremities, thus making them susceptible to frostbite in the cold!'
Utterance: 'Oh dear, that sounds serious! Well I need food the most because my children eat sooo much and I don't think I packed enough. How about I'll give you all my firewood in exchange for all your food?'
