From ignorant parents to sharing to strangers is difficult but understanding, we fear the unknown and with reason all we have to do is watch the news and even those who follow the bible and the laws there off about sharing and giving and been humane will have to acknowledge that fear is a reasonable reason for not opening the door to just anybody but mom and pappy or brother and sister and no matter how ignorant they are, they are still blood ,I know I have them in my family ,so what to do? .If the donkey don`t want water ,the fear of God is not going to make him drink it ,period so like stated here before and not just on this topic ,buy extra goods whenever you can instead of gifts buy can goods ,water ,or whatever you think is necessary for your area and hope and pray that you never have to shared it.
