I saw this lovely and helpful quote from St. Therese on the Saint Louis Crusade site, and thought I'd post it here:
We should never allow kindness to degenerate into weakness. When we
have scolded someone with just reason, we must leave the matter there,
without allowing ourselves to be touched to the point of tormenting
ourselves for having caused pain or at seeing one suffer and cry. To run
after the afflicted one to console her does more harm than good.
Leaving her to herself forces her to have recourse to God in order to
see her faults and humble herself. Otherwise, accustomed to receiving
consolation after a merited reprimand, she will always act, in the same
circumstances, like a spoiled child, stamping her feet and crying until
her mother comes to dry her tears.
