Things have changed a lot since I was young. In those days there was no social media to broadcast your every personal quirk to. You might confide something to a family member or one or two friends and that was that. Now you can tell Facebook you're suffering from PTSD and hundreds of people know your secret instantly.
But is that a good or bad thing? The "let it all out" school of thought says that revealing everything, however perverse or trivial or hateful or idiotic, might upset a few people but there's nothing festering away inside to cause inhibitions and awkwardness.
Which is fine in theory, but in practice there are many very good reasons for keeping things secret.
Someone might have told you something in confidence. If you reveal it, others will stop confiding in you. Something might be so controversial or bizarre that you can't face all the possible negative reactions, so you prefer to keep it quiet. If you're a whistle-blower exposing some sort of malpractice, you might find yourself ostracised or even sacked.
Although personally I'd like to be entirely frank about every aspect of my life, it's for reasons like those that in reality I keep many things secret. It would simply be too damaging to lay everything on the line.
My family have always been intensely secretive, telling me what's strictly necessary and keeping everything else under wraps. I know very little about my mother and father because they told me next to nothing. My sister and brother-in-law and niece are equally reticent.
Well, total transparency sounds good but can easily turn sour.
