When I am in a big group, I would take the back seat and observe everyone. Thus, I would appear to be more quiet then usual. This happens when I am with a new group. Once I am comfortable with the group, I might choose to open up more. I would also use this time to determine if I would be on the same wavelength with that certain group. If yes, good. If no, maybe I wont agree to hang out with them again.
When with my own circle of friends, I am sure I talk too much.
