Ecclesiastes 7:4-6

New Catholic Bible

⁴ The heart of the wise is in the house of mourning,
    but the heart of fools is in the house of gaiety.
⁵ It is better to pay heed to the rebuke of the wise
    than to listen to the songs of fools.
⁶ For like the crackling of thorns under a pot,
    so is the laughter of fools.
    This also is vanity.
