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: 'Seems like we are in the same boat, the bear tore our tent to shreds so we are sleeping outside and it is cold☹️' 'Sounds like a rough camping trip.  It has been pretty cold lately.' 'Is it possible I could have 3 food since I have none and 2 Firewood to stay warm and you can have 1 Firewood and 3 Water?'
Utterance: 'I do still need a little bit of food to get through the rest of the trip.  What if you took 2 food and 2 firewood?'
Yes
The speaker is negotiating for food, which they need to get through the rest of the trip. This is an example of emphasizing a personal need for an item in order to gain an advantage in negotiations. Since this utterance contains the self-need strategy, the answer is Yes.
