It’s true that what we lose may never be returned to us. However, our emphasis seems to be on what we had as not having an equal and thus being an ending of sorts. And perhaps that’s true. But life doesn’t work in a tit for tat format. Each person, each experience has its own value unlike anything else created. As such, it’s not so much that we are losing something irreplaceable, but instead moving forward to seek something else that is in a world of never ending experiences.
