I am absolutely disgusted by individuals who enjoy prying into other people's personal lives without permission. Hold on, when was prying ever with permission. Nevermind.
Euuurgh. To read their private thoughts??!! Note: It's PRIVATE. They keep it from you, for a reason you know. Wait, correction: They keep it from the REST OF THE WORLD, for a reason you know.
If you desperately need to know something, don't be a bloody coward. Step up and ASK. And if they don't want to give you an answer, live with it. It's none of your business anyway.
