Stable relationship variables

• Friendship-animosity. The degree to which an agent is in a unidirectional friendship or animosity relationship with an agent (including itself). Represented as a bias, either toward friendship or animosity, and a strength, zero to 3. Default strength is 1. There is no default bias, but it must be specified for fortunes-of-others emotions.
• Emotional interrelatedness of agents. This is unidirectional. It is akin to intimacy, but only in the sense that an agent can perceive this intimacy in relationship to an enemy as well as to a friend. This variable attempts to capture the concept that events which affect, and actions which are performed by, agents who are perceived as being more emotionally intertwined with the experiencing agent, are likely to generate stronger emotional responses in that agent. Range: zero to 3, where 3 represents a high degree of perceived emotional interrelatedness. Default 1.
