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.

Example Input: Context: 'Your needs are like mine. I have a condition that require  me to shower quite often. It is a shame but if I do not shower for 3 hours I will stink.  ' 'Well fortunately if you are camping that won't be too bad. You'll blend in with the wilderness.' 'My friends will run away. I will not be comfortable either. So how do we split what we have?'
Utterance: 'If they're true friends, they won't. I'll take 2 firewood, 2 water, 3 food.'
Example Output: No

Example Input: Context: 'i suggest we put excess in charge of working on proposition because prevention of excess is not a good first step.' 'I don't know what you mean by "prevention of excess." Can you clarify?'
