Mister, Miss, Doctor and other words are titles of respect. We usually write titles of respect in short form (abbreviation).
We use Mr. when we are talking to a man.
We use Ms. when we are talking to a woman. Some women also like to be called Mrs. or Miss. These titles tell you if a woman is married.
We use a period at the end of all abbreviations.
