In any case, my point was that R’ Matisyohu encouraged the child
to take a particular food because it tasted better, which does
not fit with an idea presented in this thread by a poster.
There’s a story about Rav Eliyahu Dessler taking out a large sefer
and looking into it before telling a woman that her fish, which
was lacking a liver, was kosher (there is no halacha of a t’reifah
regarding fish). He explained to a talmid who was standing by that
if he did not treat every question with respect, people would
hesitate to come to him with their questions.
