“Don’t you see? You and he might never cross paths again. Of course, a chance meeting could occur, and I hope it happens. I really do, for your sake. But realistically speaking, you have to see there’s a huge possibility you’ll never be able to meet him again. And even if you do meet, he might already be married to somebody else. He might have two kids. Isn’t that so? And in that case, you may have to live the rest of your life alone, never being joined with the one person you love in all the world. Don’t you find that scary?”
