Let's say a Soviet exchange student back in the '70s would go back and tell the KGB about people and places and things that he'd seen and done and been involved with. This is not really espionage; there's no betrayal of trust.
I do like having my ears pierced, because there's a lot more choice in pierced earrings than there is with clip-ons, and they're a lot more comfortable to wear - Sometimes I completely forget I've got them in and end up going to sleep wearing them.
