Ambivert- Not either one, yet some of both. I crave social settings, but only until I tire of them; I cherish solitary pursuits, but only until I become restless for interaction. I have no inhibition for speaking, yet I respect the value of listening. I tend to think things through, but usually also seek counsel in matters of consequence.
I'm pretty much the same. I'm an introvert and find it necessary to have a certain amount of time alone. I don't like parties or large gatherings and like hanging out with only one or two other people, a the most. But work does require me to be very social and interactive with my clients.
