Well I will continue to take the easy way and enjoy the stories writers have shared. Some that I enjoy have passed, but I still have their story pages bookmarked since I will read them again.
Although like I stated above, I will continue to enjoy their stories in the future.
As for the unfinished stories, don't focus on what'll never be. Instead, focus on what they offered. We have a LOT of unfinished works of brilliance, and while we'll never see them concluded, we can enjoy them for what they are, and imagine our own endings.
Check out the list of wonderful, incomplete stories and see what I mean. Writing stop writing, or give up on stories, for a variety of reason, but it doesn't mean the stories being available. The hope of all authors is that their words will live on after they've left the earth, speaking to future generations.
