A more thorough explanation:

Definition: Propinquity refers to the state of being near or close to something or someone. It can also refer to a close relationship or kinship, such as family ties or blood relations.

Examples:

• Living in the same neighborhood as someone can create a sense of propinquity, even if you don't know them well.
• Family members have a strong sense of propinquity due to their shared blood and history.
• Working in the same office can create a sense of propinquity among coworkers, even if they don't socialize outside of work.

The examples illustrate how propinquity can refer to physical proximity, as well as emotional or relational closeness. It can be used to describe both positive and negative relationships, such as close family ties or uncomfortable work situations.
