When people ignorantly pry in peoples lives, what r some ways to teach em some lessons, that would concrete the message to mind their own?

The old "Nigerian scam" is a good standby.

for nosy people just say..It’s better to have your nose in a book than someone else’s business.

It’s an odd thing how some people have to be all up in your business, kind of like a wedgie. Now that’s some bad crack. chances are, if you have a meddler on your hands — especially if they’re an adult meddler — there’s nothing you can do to change them.You would be very surprise with how much positive changes that you could make in your life, if could make it your top priority to mind your own business.To be busy minding other people's business, is to leave one's personal business unattended to.

Since you haven't given us any details of this ignorant prying, we wouldn't have any idea how to teach these strangers any kind of lessons. Is it possible that you're the who's responsible for the prying?
