DD always said that as well. But her motivation was feeling different and disconnected from other children. One thing that helped us was connecting her to a friend, also HG/PG, who was very comfortable with her giftedness. She was just a bit older, accelerated, and was an amazing role model for my child. We were lucky to connect, but we did make a concerted effort to find similar-LOG age mates for her so it wasn't all coincidence.
I agree with Dude that the motivation for their asking is important. Being asked for help can make a child feel good and provide a connection to others... or it can feel even more isolating. If the attitude is "you're so smart, I bet you can't figure this one out" that can't feel good.
Maybe dig a little deeper?
