Living around Amish folks, I guess it never dawned on me that people wouldn't understand them.
A friend of mine was surprised to see them riding in a van and when she saw the hitching post at the grocery store, she was surprised to hear that Amish people could go to grocery stores. When I said that of course they could and why wouldn't they, she thought they couldn't because the stores had electricity. At the time, I thought she was a dope. But it makes sense, I guess...if you don't live near something, why would you know about it??
Amish people can do most everything everyone else can do. The jobs, though, have to be purposeful - manual labor, necessary things. The clothes are fairly plain and their homes don't have all the conveniences we do...but they go places, use things, and have fun just like everyone else.
I like the Amish a lot. We eat in their restaurants, drink in their bars, etc. If I could, I'd get them to drive cars (because I hate being stuck behind the damned horses for miles

), but there is a lot I admire about their culture...they're just as nice as anyone and often a lot less phony.
