With the Ascendant in Sagittarius, the person may present themselves with charm and an overwhelming friendliness. They value clear rules, although at times they want to define and change them according to their own judgment. If the partner accepts each change without talking it over, they may find new conditions appearing again and again.
Behind that untamed appearance and a humor that sometimes wounds, there may also be a need for guidance and clear limits. Before accepting a new change, talk with your partner about the agreements you both want to keep.
