The antonym for the phrase "more out of line" would be 'In line'. This means that an individual is behaving in an appropriate or proper manner, adhering to the rules or norms of a particular situation. Being 'in line' may entail abiding by an established protocol or following a set of rules, behaviors, or expectations. Being in line is important, as it shows that one is respectful and considerate towards their peers, colleagues, or superiors. Conversely, being 'more out of line' would highlight a disregard for the rules and norms, and may lead to negative consequences such as social ostracism or reprimands.
