Swiss mentality varies significantly in the German, French and Italian speaking areas.

 The Good:
1)Civilized in general
2) Educated
3)Trustworthy when it matters
4)Well organized and on time
5) Very animal friendly
6)Clean. With one/herself and with nature
7)Curious. (careful here. Swiss tend to want to know all about you but when it is their turn, good luck finding out more than name, age, work and where they were born.)

The Bad: 
1)Stubborn. We CH are always right, even if we are wrong.
2)Like to start conflicts (without use of force or foul language) over small ridiculous reasons, aka better knowers.
