the.com/complacency

The pat on the back that turns into a knife, slowly.

means A quiet, self-satisfied contentment with how things are going — comfortable enough that you stop checking for danger.

from From Latin complacere, 'to please greatly' — com- (intensive) plus placere, 'to please' (the same root that gives us 'please' and 'placid'). So at its root, complacency just means being thoroughly pleased with oneself; the word's slide into 'dangerously self-satisfied' is a later English development, as being too pleased with how things are going came to be seen as its own quiet hazard.
