I could hear them long before they arrived, a massive flock of crows searching for a roosting spot, alighting and flying and alighting and flying in a black chaos cloud at the top of the tallest tree across the street, swerving and diving and cawing for position, voices raised in a million mixed emotions, until some hidden directive informed them to move on to better prospects and they vanished into the northern horizon like an undulating shadow. Thursday night is my favorite night of the week and this week is no different, so after our usual Subway I am now finishing out the last of the tasks before the weekend.
