Banana Yoshimoto said this quote

I’ll never be able to be here again. As the minutes slide by, I move on. The flow of time is something I cannot stop. I haven’t a choice. I go. One caravan has stopped, another starts up. There are people I have yet to meet, others I’ll never see again. People who are gone before you know it, people who are just passing through. Even as we exchange hellos, they seem to grow transparent. I must keep living with the flowing river before my eyes.
