You have to be sharp to keep up with the changing social mores. While "don't stare" "don't point your finger" are withstanding the changing social landscape, "don't eavesdrop" has not. Hundreds of thousands of Web sites now specialized in eavesdropping as entertainment.
One example, as reported by the Sun Sentinal...
"Today, I was working at Publix ringing up some 70 year old woman. She says ‘Man, you're a fast cashier, I like my men fast!' and then gives me a wink. I got really nervous and didn't know how to respond, so not thinking, I quickly said, ‘Yeah, me too.' FML"
