Don’t you hate it when you have a great friendship, with great talks and great times, and all of a sudden, the person you were just having a deep talk with is just another person you say hi to? Friends come and go, but when realizing that things don’t even seem the same as they were, it sucks. It’s happened to everyone, and everyone dislikes it, yet why does it happen? What causes people to fade? There are a bunch of possible answers to these questions, some more understandable than others. My advice, just go with the flow. If you’re fine with turning a best friend into an acquaintance, that’s all on you. You could always try taking another shot at a possibly longer lasting friendship. Just don’t let it be painful to see a face and think “we used to be the best of friends”.
