The things we do for love make us do stupid things. We believe liars, put our faith in unfounded realities, and even take up arms, and volunteer to sacrifice our lives. Does one need to itemize examples? Love, that which makes us feel our lives are complete, is a tool for some, an elusive destination for others, and many things to many others. It is the essence of religion, where people fallow butterflies, and train their children to do the same.
The things we do for hate. I will not go into detail, from my reference point is sad but very much a factor in much of human behavior.
Should we raise our children to be uncaring? I have lived for love, never for hate. Sometimes seems 2 sides to the same coin. Is the life of a hermit the best choice for the future?
