Read the excerpt below from Little Women and answer the question. "That is perfectly natural, and quite harmless, if the liking does not become a passion and lead one to do foolish or unmaidenly things. Learn to know and value the praise which is worth having, and to excite the admiration of excellent people by being modest as well as pretty, Meg."
What does Marmee mean when she tells Meg to enjoy the praise as long as, “the liking does not become a passion and lead one to do foolish or unmaidenly things?”

She worries that Meg’s vanity will cause her great pain.
She hopes that Meg realizes there are more important things in life than fitting in at any cost.
She believes that a woman should not be seen in public with a man unless she is engaged.
She hopes that Meg never conforms to the popular crowd.
