When I was little and children in school shared secrets, often the chant "Secrets, secrets are no fun unless you share with everyone," was heard. When I was a bit older, around ten, secrets were freely told to friends but also freely shared by everyone: I guess the chant really put it into our skull that secrets must be shared, but it wasn't fun when everyone knew about it. Now at my age, we've learned to keep secrets. Actually, let me rephrase this: A few friends of mine and I are able to keep secrets. Most of the kids, however, are still at the stage where they must tell everyone their friend's biggest secrets. At the moment, I'm harbouring a huge secret. It's not my arthritis, as I'm somewhat open and free to tell people. It's not my love of rather geeky things either, though I don't tend to display it for all to see. Anyway, some secrets I try and overcome my fear of by just saying it. Usually, it works. Nobody thinks my secret is funny (if it's serious) and laughs or judges me, typically anyway. Actually for the most part afterward it isn't a big deal anymore. But not with every secret of course: some are meant to stay secret.
I think the issue most people have with secrets is not the secret itself but fear of being judged by it. For example, some people are very embarrassed of their secret of being born out of wedlock, especially if they are very religious and don't want to be seen as a sinful person. Or some people keep their religion a secret because their friends are atheist and they don't want to be judged based on this fact.
I don't know what the point of this post was, just that I wanted to talk about secrets.
