Born at this point in Libra season
This person was born in the final stretch of Libra, when the season is already moving toward Scorpio and most of the weighing has been done. Choices can feel overdue by then rather than open. Others see someone with the facts lined up who still pauses before speaking. Inside, that pause is a wish to make the other side feel fairly heard before saying what they think. It is a habit of checking the ground first, and it suits a late October birthday.
