This is something I think about some times. And you really can't talk about it with acquaintances that might enter your orbit periodically. Prospectively, this is your pool of available friends should that type of relationship develop. And this isn't about how to meet people or where to meet people. It's about the difficulty of transitioning from mere acquaintances to friends. Why is it so difficult to make that transition? I can imagine from my perspective being a transplant from a different region to new region that there are several possible reasons. First thing that I reason is that after a certain age, you've settled, filled your friend slots, and have an established routine based around your interests and your existing friend's interests. That means a person wouldn't have a whole lot of time resource and energy to develop new friendships. Another could be cultural misunderstanding and even prejudice. I'm sure with time, a few other reason may occur to me. What do you guys think? Why is it difficult to make new friends after a certain age?
