Etiquette isn't just something you need on formal occasions. It's a blueprint for how to behave every day, in every situation, to make interactions between people productive and pleasant, with no ruffled feathers, misunderstandings, or hurt feelings. It helps you smoothly transition from college to corporate life, and from professional obligations to personal ones. Etiquette doesn't exist to add a layer of extra rules to life - it's there to guide us to treat one another with kindness and consideration every day.
