Though we have not made a deliberate survival plan, we routinely maintain a lot of extra food and household supplies. Often, a neighbor or two will "borrow" something, which we gladly give. We are an elderly couple with a very large family living in the neighborhood. If there should be a disaster (G-d forbid), how should we address the almost certain requests from family and neighbors for some of our supplies? Are there and established/suggested guidelines (religious, governmental, organizational) for assisting others? We never hesitate to help in normal times. How should we act in extraordinary times?
