परपरिवादः परिषदि न कथंचित्पण्डितेन वक्तव्यः |
सत्यमपि तन्न वाच्यं यदुक्तमसुखावहं भवति ||
- पंचतंत्र - काकोलूकीय
A wise man knows how to behave in a gathering. He knows well that he must not ridicule/talk harshly to any one (even when they are his opponents). Some times, even the truth must not be told. Especially when it is sure to hurt some one.
