When we say that human beings are social, we impute that they interact with one another. The interaction is in most cases patterned and institutionalised so as to regulate human behaviour. when through institutionalization certain behavioural patterns are maintained in a society overtime, one can conveniently analyse the structure of that society. Therefore, when we speak of the social order, we pass on the meaning that social relations are patterned in specific ways. The specific ways could be ideal, which refers to what ought to be, or behavioural which is the actualization of what ought to be.
Regulation of human behaviour?
I think what others ought to see from others if it's "just fine" in judgment, it's being normalized. And in this society, you cannot regulate everyone's behaviour unless you're the one who creates law for them to follow and have certain instructions what must done and what mustn't be done.
