Director and secretary

There was once a secretary who worked in an office, and she loved to make the manager fall in love with her.
Once she went to the office, tired of the elegance, make-up, and coquetry, but it did not produce any results.
And one time, the manager came and said to her, “What do you do in the evening on Sunday off?”
And she said to herself, “By God,” it finally happened. She responded quickly. Nothing, professor.
He said to her, “Okay, go to sleep early because you come late to work every Monday morning.”
