instruction:
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.
question:
Context: 'Yes, how about you! We are headed to Joshua Tree NP to do some rock climbing and hiking. ' 'Ooh rock climbing! I'm definitely scared of heights, so that's out for me. I'm heading to the Puget Sound to camp near the ocean.' 'My wife is from the puget sound. Was just up there a month ago.  I am looking to take the food and water.  We have a large group and will be active.  We will have some hot and dry conditions in the desert. Some are high school age students with big appetites.  What are your preferences.'
Utterance: 'I was definitely looking to have food and firewood most of all. There are plenty of places to collect rainwater and get fresh water in Puget Sound, but we're lacking in food and will need firewood to start a campfire at night.'
answer:
Yes


question:
Context: 'I don't have any problems letting you have all 3 waters. Would you be willing to give me all 3 firewood? I need extra to keep me warm as I get cold easily.' 'That's a little tough for me but if we can come to an agreement where I get 2 of the food, I'd be willing to play ball.  We both deserve a good camping trip, after all.' 'That's true. We both deserve a good trip. Why do you need more food?'
Utterance: 'Because I planned to go hiking and it wouldn't leave me time to chop much of any myself.  Even if I did, I'd have to carry it back and that's obviously not very smart in this heat.  But if I had the extra food, I'd be willing to inconvenience myself with getting firewood and cutting my hike a little short because I know the firewood is important to you.'
answer:
Yes


question:
Context: '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?' '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?' 'If I only had 2 Food and 2 Firewood, I would need 1 Water to wash the food down and put out the Fire when needed'
Utterance: 'That makes sense.  I just want to make sure I don't run out of supplies on the trip.'
answer:

Yes
