The good ones, they always go away. Why is that? Why this recurring pattern? Random, unlikely encounter. Lives entwine. Bonding. Trust. Doubt. Trust again. They give you somethiing you need without even knowing they are giving it to you. If you think about it, you are probably doing the same for them, but mostly you just see it from your point of view: they were not here, they are here, I cannot imagine them not being here.
And then they go. The good ones, they always go away.
