What the first decan of Aries is read as

The first decan of Aries is read as Aries twice over, Mars with nothing to soften it. People here tend to decide fast and apologise fast too. In love they say it first, and at work they would rather fix a wrong start than wait for a right one.

What the number 3 adds

Numerology reads a birthday that comes to 3 as the mark of a talker and a maker. It tends to mean an easy way with words, a need to express what you feel, and some trouble finishing what stopped being fun.
