Answer:
one must not tell to everyone and publicly what happens privately.
Step-by-step explanation:
The above phrase is a sentence from the book The Scarlett letter by Nathaniel Hawthorne. The marketplace in this phrase means the public while the forest can be likened to privacy. It simply measn that one should keep thingd to himslef as much as posisble rather than telling it all over the place.
