If something is special then it would be cherished. If I have to let it go for some reason, it only means it's time to part ways as the journey together comes to an end, which is destiny.
Saying that it was not special is undermining my own skill to cherish.
We cannot be careful all the time which does not mean we cared less.
Cherishing all the time is Obsession, which is not care as when the time comes it would happen in split seconds.
Sometimes, one way or another, people just lose things. Life can get in the way, mistakes can be made, unexpected outcomes could be had, etc.. i think the stuff that is really special and worth having can't be bottled up locked away to be protected. It has to be open and free allowed to be lost with the trust and faith it won't be.
