December 4 in profile
By 12° Sagittarius has found its footing. This is the typical archer: frank, mobile, fond of meaning and slightly allergic to routine. The second decan adds Aries through its sub-ruler Mars, so preferences become strong opinions and opinions become decisions made on the spot. The mix is warm and decisive, with fire on two levels and little patience for half measures. A December 4 Sagittarius knows what they like within seconds and can usually say why.
Their style mixes origins. A jacket from a market in another country, boots built for weather, one bright scarf that does all the talking. They choose clothes they can move in and then forget about. Fussiness leaves them cold, but a story behind an object wins them over immediately. The wardrobe is small, well used and slightly battered at the elbows.
Home works as a base camp. Rucksacks live by the door, there is always a spare bed for a friend passing through, and dinners stretch late around a crowded table. Family ties stay strong but loose; they phone at odd hours and turn up with presents from somewhere far away. One fixed ritual, a weekly meal or call, gives relatives something they can rely on.
