Put another way, a very wealthy person might stay quiet when other people are talking about how they're going to pay for college. In this case, the person is being polite. S/he has something the others don't, and keeping quiet in this situation avoids making them feel bad or inadequate. Speaking up would just remind them about something they might already feel rotten about.
So in this context, I can see that keeping quiet about giftedness is appropriate (most obviously if the talk is about a child with developmental delays, but even if everyone else is just average-ish).
Yes, I'd have to mostly agree with this.
I do occasionally find it a drag to have to censor what I say, but at the same time, I also recognize that to not censor would be iffy in terms of social appropriateness.
When other people are being braggy--it's okay, because I don't want to be LIKE those braggy people. However, sometimes an accomplishment is shared openly and with joy and other receive it purely and openly, and that's the only time it feels a little hard.
(It's probably worth mentioning that my kids are extroverts and tend to openly display their smarts. I can't really hide their lights under a bushel anyway.)
The worst time for us so far was when we were deciding whether to switch DD to the gifted magnet. I had to be somewhat open because everyone knows what the school is, and I got many weird responses.
