What is one source of friendship mentioned by the individual?

One source of friendship mentioned by the individual is from a close group formed during middle and high school. This connection typically offers a sense of continuity and shared experiences, as friendships developed during formative years can be particularly strong and influential. These relationships often involve deep emotional ties and a strong understanding of each other's backgrounds, which can create a lasting bond. The familiarity and shared history that come from experiencing similar life stages together contribute to the significance of these friendships, making them a major source of support and connection in an individual's life. The other options represent potential sources of friendship as well, but they may not carry the same depth of shared experiences and emotional investment as those formed in school during adolescence.
