They are actually quite nice people. Depending on whether they are old order or not, you will find the women don't speak much in the old order groups, especially not when men are around. Otherwise, they have a great deal of common sense and see a lot of joy in everyday life.
They are different in that they ten to not use modern technology. It doesn't mean they can't, but they try not to. For example, they would not refuse a ride in an ambulance or modern medical for a serious farming accident, orserious illness. However, technology is not part of their everyday life. For them, life is a great deal like it was for all of us back in the 1800s.
There are some modern developments of old technology that they will use, however. A hand crank washing machine is just fine to use. Modern textiles, sneakers, modern undergarments, pellet stoves instead of the common woodburning ones, etc.
They grow a great deal of their own food, but I have spoken to several who said they will, when needed, buy meats and vegetables from modern butchers and farmer's markets.
