Responsa for Bava Metzia 60:13
בה זו קבורה היינו גמילות חסדים לא נצרכה אלא לזקן ואינו לפי כבודו
The question stands. Raba said: Where one would lead back his own, he must lead back his neighbour's too. And where one would unload and load his own, he must do so for his neighbour's.<span class="x" onmousemove="('comment',' V. Deut. XXII, 4, which is interpreted as meaning that one must help his neighbour to load or unload his animals. Here too he is exempt if it is inconsistent with his dignity, and Raba observes that the test is whether he would do this for his own. ');"><sup>5</sup></span> R. Ishmael son of R. Jose was walking on a road when he met a man carrying a load of faggots. The latter put them down, rested, and then said to him, 'Help me to take them up.' 'What is it worth?' he enquired. 'Half a <i>zuz</i>,' was the answer. So he gave him the half <i>zuz</i> and declared it hefker.<span class="x" onmousemove="('comment',' 'Ownerless.' ');"><sup>6</sup></span>

A. A dowry gift becomes the property of the donee only if the marriage takes place. Therefore, neither A nor his daughter has ever gained title to B's money, and A must return the principal plus the interest to B. Even if B expressly stipulated that he will forfeit the 15 pounds if the marriage does not take place, such a stipulation is considered an Asmakhta and is not valid. B, however, must pay A for his trouble in managing B's investments.
