"The thing or condition for which one wishes is seldom if ever what he expected it would be, or if he gets just what he wanted it will bring unexpected difficulties or sorrow, or the getting of the wish will change conditions that the wisher does not wish changed, or it will lead or require him to do what he does not wish to do. In every case the getting of a wish brings with it or causes some disappointment or undesirable thing or condition, which was not bargained for at the time of wishing."
