Answering the door, as an actor you will need to have this skill. Here’s how to do it.

As an exercise, answer the door EXACTLY like this substituting “Stella” with the name of whomever is at your door. It’s OK to use “my (darling) neighbor,” or “the (darling) mailman” if you don’t know their name but it is not OK to omit the word “darling.” Answer the door exactly this way for six months to a year.
