Season 9, Episode 1: Going Going Gone

"Dying changes everything. There is the emotional fall out, sure. But there's also the practical stuff. Who's going to do your job? Who's going to take care of your family? The only good thing for you is you don't have to worry about it. People you never knew would be living in your house, working your job... the world just keeps on going without you."

"They say death is hardest on the living. It's tough to actually say goodbye. Sometimes it's impossible. You never really stop feeling the loss. It's what makes things so bittersweet. We leave little bits of ourselves behind, little reminders, a lifetime of memories, photos, trinkets, things to remember us by... even when we're gone."
