1. Longevity. The longer you’ve been friends the more likely you’ll be friends in the future.
2. Trust. Trust in a relationship is anti-fragile. The more times trust is partially damaged but restored, the stronger it becomes.
3. Meaning. The story “we met while looking for friends to do MDMA with, and now we are attached” is cute when you’re 23. What those people mean to you is that you are lovable and able to form bonds out in the world. Good! But shallow.
TLDR; it may be an effective way to have intense but shallow and short-lived connections
