Conforming to the standard or the common type; usual; not abnormal; regular; natural.
Behold the definition of normalcy. Conforming to the standard or the common type. In shorter terms meaning being apart and alike with society.
characterized by fixed principle, uniform procedure.
Stating we are all the same, perhaps in operation and structure.
We are all neither normal nor are we regular in this sense. If you do not follow the changes of society, it does not make you an outcast, or abnormal. And we are all unique, not one of us being exactly the same. Structurally, yes, we are human, we all have similar functions. But never the same. Appreciate what you have and can offer the world. Using it and then together we can become the true definition of regular and normal.
