The phrase "keep arm's length" is an idiomatic expression that means to maintain a safe or cautious distance from someone or something, usually for the purpose of avoiding potential harm, conflict, or negative consequences. It derives from the literal notion of keeping one's arm extended, creating a physical boundary or space between oneself and others.
In a figurative sense, "keeping arm's length" involves consciously refraining from getting too emotionally or personally involved with someone or a situation. It implies maintaining a certain level of detachment or reservation, where boundaries are established and interactions are limited. This can apply to relationships, business dealings, or any situation where a level of caution or self-preservation is desired.
By keeping arm's length, individuals aim to protect themselves from compromising situations or potential harm by maintaining some degree of distance, either physically, emotionally, or psychologically. It highlights the importance of self-care, personal boundaries, and maintaining a sense of control over one's own well-being.
While it can be seen as a defensive approach, "keeping arm's length" does not necessarily entail complete avoidance or hostility toward others. It merely suggests the need to be vigilant, cautious, and mindful of personal boundaries in order to protect oneself from negative or detrimental situations.
