My response is always "if he was a freshman in high school, and he played basketball like Michael Jordan, would it be fair to him to play with the freshman or with the varsity?"

When sports are involved, it's ALWAYS a different response.

Of course, then they move on to maturity level, saying he wouldn't be mature enough at this age or that age which ALWAYS cracks me up because people who have NO idea how old DS is or what grade he is in almost always comment on his amazing maturity level - they automatically assume he's 7 or 8 (just short).
