I hear similar sort of stuff once in awhile, but it is usually from one or two people who I have come to expect such statements from.
What I experience more often is that I cannot feel free to comment on my DD at all because her "normal" so far exceeds other kids normal that it seems to make people insecure. And I am not talking about bragging, I am talking about answering a simple question, like if my neighbor asks me what reading level my DD is at, I can't answer because if I do answer truthfully, I get some horrified look of disbelief or feel like they think I am the person who is ranting and raving that my child is gifted.
So, we just keep all achievements on the down lo over here, while everyone else gets to over celebrate the small stuff. LOL
