Love rapidly escalates trust without needing shared community support [causal]
The striking thing about a love relationship, whether it is mutual as between two lovers or more nearly one-way between a parent and child, is that the trusted genuinely encapsulates the interests of the truster in the trusted's own interests. Moreover, this is commonly true ab initio for the mother of a newborn child, and it is very nearly true ab initio for lovers who fall suddenly in love. The lovers need not have known each other for very long, and they need not have a rich array of associates in common to protect them in their risk taking with each other. Their love allows them to escalate the risks they take very fast and relieves them of the need for support from a larger community. Falling in love moves everything ahead much faster, and the thrill of such momentum may even enhance the love just because it is associated with the beloved.
