Born at this point in Aquarius season

This person was born late in the Aquarius season, when the broad ideas of winter have already been argued over and the slower work of making them real has started. A friend brings a bold plan over coffee, and this person listens closely, then asks which parts will still stand after a rough month. The question is not meant to dampen the spark. It comes from a wish to see things finished, and it sits alongside a readiness to change course when the evidence says so.
