Wisdom of Ben Sira 13:10-12

New Catholic Bible

¹⁰ Do not be too forward or you may be rebuffed,
    but neither should you keep aloof lest you be forgotten.
¹¹ Do not try to converse with him as an equal,
    or trust his effusive words.
The more he speaks, the more he is testing you,
    and while he smiles he is evaluating you.
¹² Those who do not keep your secrets are cruel,
    and they will not spare you injury or imprisonment.
