Your first name of Sis creates an idealistic, charming, expressive personality. You are too sensitive and too easily hurt and offended, but you can always be appealed to for sympathy and understanding. To please others and receive approval and affection is important to you; but when they let you down, you tend to become temperamental and self-pitying. You have the desire to help wherever possible. Being inspirational and imaginative, you are drawn to the arts, music, drama, or where you are assisting or mediating on behalf of others. The problems of others can also affect you through a sympathetic condition which creates a susceptibility to sickness and extreme nervous tension. You want everyone to be happy and agreeable, and your environment to be harmonious and free from acrimony. Often you find yourself in the position of the mediator, where you are settling disagreements, or you find you are going along with something you do not agree with, just to keep the peace. It is difficult for you to say "no" and mean it. With good intentions, you make promises but do not always keep them.
