Your parents threatened you when the decision was to stop sharing. I honestly believe that's a horrible place to put a person. What is sharing but giving? When people give give give. Not only do the people around them become addicted to it. But the giver becomes empty. I am not a fan of sharing. I trust instead in participation. If there is to be a transaction. You should be asking, "What's in it for me?" While building a foundation sand alone won't hold up a home. It requires several different elements. But how strong is the house if the maker of support chose to steal the energy from someone or something that felt empty?
