Of Giving and Receiving

Occasionally, it happens that a child may give someone mishloach manos and not receive anything in return. This may be because the intended recipient isn’t home, or they ran out of mishloach manos, or for some other reason. The child fulfilled the mitzvah in the choicest manner; he didn’t receive anything in return, yet he still fulfilled the mitzvah.
Still, the child feels cheated. He worked so hard filling a bag with nosh that his parents bought with their hard-earned money. The child resolves that the next house he goes to he will give his mishloach manos using the halachic principle of “matanah al menas l’hachzir.” He will give his friend a bag of nosh on the condition that the friend returns it.
The child’s father may tell him, “That’s ridiculous.” The child may counter, “I overheard you learning daf yomi. Rava says in Kiddushin (6b) that ‘matanah al menas l’hachzir’ is considered a bona fide present. The present is given wholeheartedly; the recipient only has to fulfill one minor stipulation: he must return the present.”
