Its a good day on a construction site when they sweep, rake and otherwise clean up all the debris and everything looks clean and new.
Its a good day when you acquire the rocks you need for the fireplace and convince some children to clean them off for a bit.
Its a good day when windows start going in.
Its a bad day when you realize you will not be using rocks for the fireplace and you did all that work for nothing.
Its a bad day when in the process of cleaning up you discover you can't find your phone line and as a result your internet no longer works.
But if none of these things happened we wouldn't be making progress and this wouldn't be an adventure.
