You agreed to dog-sit for your neighbor while they were on vacation, but due to an unexpected emergency, you had to leave town suddenly, leaving their dog in the care of another, less experienced friend. Write a letter to your neighbor apologizing for the situation. You should include details about: - the circumstances that led to your unexpected departure - how you arranged for the dog to be cared for in your absence - express your concern for the dog's well-being and offer to compensate them for any inconvenience.
