Q: The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
Context: 'Hi  I have an extra guest that will be camping with me and was wondering if you had an extra food package that you could spare?' 'I don't have much food, but you can take one package and I can take two? '
Utterance: 'thanks  that would be great!  I also need an extra package of firewood, I will probably need it cooking.  Do you have a spare package of it as well?'
A:
Yes
