You are just about to get comfortable in your room and maybe take a nap when there is another knock on your door. You are really getting tired of people interrupting you just before you get a chance to rest for a little while. You know what you will find when you open the door. It would probably be Lady Elizabeth giving you another order.
You opened the door and there she stands ready to give you another command.
"Yes?"
You can see the shock on Lady Elizabeth's face at your reaction but she quickly returned to normal and talk as if she is not noticing your attitude.
"Dinner is served and you are required to attend dinner in the dining room. You are required to be there, right away"
"Of course, it is required of me to be there right away. What other way could there possibly be?"
