When my now-11 year old said something similar to me -- he actually said he wanted to be average -- I focused on the "we are who we are" side of things. He's also unusually tall (5'8" at 11), so I joked that the only way to make him average would be to cut off his feet at his ankles and that clearly wasn't going to happen. And I wasn't going to cut out part of his brilliant mind to be average, either.
