Maybe it's just me (I suspect not though) but I hardly ever mention my 'hobby' of writing. Friends and family are not really interested and I have seen their eyes glass over if I ever mention it.
I was just reading my first ever post on here (about the plagiarizing of my script) and even there without knowing anybody on here, I was a little embarrassed about telling my story. https://www.comedy.co.uk/forums/thread/18648/
In my early days of writing, I had some jokes printed in a local newspaper. They were topical and about local events. The paper (which was a free weekly edition) asked if they could print one each week. I of course agreed but my wife was embarrassed because they printed my name for everyone too see with every one.
You'd think I had paid for a half page add to tell everyone I was a closet transvestite.
Even when I sold my first gag and got the payment receipt, if I showed it to anyone, it was met with feigned interest at best and embarrassed incomprehension at the worst.
Is 'I am a writer' a dark secret in your circles?
