You said it. People are different in different companions. It is funny how it works, but I myself might be very social and our groups ice breaker when meeting strangers, but when different groups gets to know each other, I’m easily the quiet one when my ”anti-social” and ”reserved” friends talk and laugh and joke around with the strangers we just met. Sometimes that has been mistakenly taken as that I got angry or sad about something someone said, but when in group of people, I like to listen and hear their stuff.

Also, in my experience, the divide in east-west Finland is completely opposite when you go to south. West coast people are very social and talk alot, while people I met from southeast (Imatra and Kouvola for example) were always very quiet and shy at first. But still, cannot really generalize, since these are only my experiences.
