What it means
Your manner is lively: questions, jokes, a quick reply. You seem younger than your years and more curious than others. Much in life opens up through words.
The flip side is nervous fussiness and a habit of saying more than needed; it's hard to stay quiet during a pause.
This isn't about you if from the first meeting people take you for a quiet person and say you're “closed.”
How to check it on yourself
Check it against your past — write your answer down before you look at the chart.

What should match. Ask two or three acquaintances about their first impression of you. At least two will mention talkativeness, curiosity or quick answers.
When it’s not about you. Two out of three will recall quietness — this isn't about you.
