Humans (Starway) are communitarian. Humans like to say that their species is a large family the size of twenty billions.
- Legally, a human only have one registered parent. Inheritances are passed according to the parent's will. If the parent left no will, then the inheritances are divided equally among the remaining children.
- Biologically, a human have two parents, Central Authority maintains a genealogical database to prevent genetic inbreeding.
- Culturally, a human have a "group" of parents consisting of their legal parent, the parent's sibling, and the parent's acquaintance.
Due to their technology, humans stop aging past certain point. What looks like a couple of siblings might in fact be a child and his/her grandparent. Most humans still live with their parents even well into adulthood. It's not uncommon to see a human living with his/her children until their death.
A lot of humans are engaged in a romantic love with their own family members. Most other species are unnerved (and some are outright disgusted) with this.
