These are some great ideas! I had thought that if I give something extra that I might have, to a neighbor and the neighbor’s neighbor hears about it, then I am in trouble. As this multiplies, you can get in a lot of hot water, so to speak. So your idea of trading is a good one. However, how do you disguise the fact that you have something in the first place? I would think that someone who has a gun won’t need to have something to trade. All he needs to know is that you have something in the first place. How do you deal with that?
