Musar for Bava Kamma 174:5
במאי אוקימתא לקמייתא בשאין סמוכין על שלחנו אי הכי אימא סיפא החובל בבתו הקטנה פטור ולא עוד אלא אחרים שחבלו בה חייבין ליתן לאביה לדידה בעי למיתב לה דבעיא מזוני
Is it really a fact that in the case of a son who has already come of age the father has to compensate him straight away? [If so,] a contradiction could be pointed out [from the following:] 'If one injures the sons and daughters of others, if they have already come of age, he has to pay them straight away, but if they are still minors he should make for them a safe investment [out of the compensation money], whereas where the sons and daughters were his own, he would be exempt [altogether]'!<span class="x" onmousemove="('comment',' [Does the latter ruling not apply even where the sons and daughters had already come of age, in contradiction to the ruling stated in the former teaching?] ');"><sup>8</sup></span> — It may, however, be said that there is no difficulty, as the ruling here [stating exemption] refers to a case where the children still reclined at the father's table,<span class="x" onmousemove="('comment',' I.e., were maintained and provided by him with all their needs; cf. B.M. 12b. ');"><sup>9</sup></span>
