When a tradition died in your family were you to blame or would you ascribe the blame to someone else's actions?

It’s official, tonight it’s bah humbug for Christmas. No one prepared the traditional Christmas Eve meal, therefore there is no Christmas in this house anymore. I was not present to do it as I was required to be at work. I fully expected the person who was home to handle it, yet she chose not to. I don’t actually know where the other members of the household actually are, as no one has left me any notes as to their whereabouts.

So now I feel guilty, as if it is my fault for working on Christmas Eve.

How does one let go of the past when there is no future to build?
