After the age of 21, when I started to know people in the world, I never told them that I was a JW and more recently that I've left the JW's. I was always embarrassed of it. I was worried that with the truth being such a small world, if I said something to someone in the world, the next thing they'd be telling someone they knew who was a JW. I would just never refer to it and if JW's ever came up in conversation (on the two or three occasions in the last 15 years - cos they're really not a topic people ever talk about) I'd listen to the odd strange stories and not say anything.
I did feel like I was holding something back but also it just wasn't relevant to the conversation or the other person.
In terms of meeting interesting people - I've been lucky enough through hobbies/work to rub shoulders with lots of truly amazing people - I could list 20 or 30 that would be recognised by most on this forum - and the few minutes I may have spent with them were not spent talking about my childhood - know what I mean?
When I had to go for interviews recently - many were quite surprised I had reached the level I had without a degree. I'd always waffled around it in the past but I was honest for the first time and admitted my parents were strongly religious and against higher education so I didn't get the opportunity of university. I got the job, been promoted and no-one has referred to it since.
It's a huge deal that most JW's have/are gone/going through and people you meet will be interested in it, but keep it brief and let them ask the questions.
