Answer:
This is an example of the strength of weak ties.
Step-by-step explanation:
In sociology, we can think of strong and weak ties. Our strong ties are the people whom we know well and meet often. The weak ties are our acquaintances and people we rarely meet or communicate with. The strength of weak ties lies in their power to function as a bridge between social groups. Weak ties, such as the one described in the question, may have important information and work as a link between people and groups. Therefore, maintaining weak ties proves to be of great help.
