My DS8 comes off as arrogant as well. The issue with him is that he is extremely literal. When asked why he is accelerated 4-6 years, he'll answer "because i'm really smart". It's not bragging in his mind but rather just the facts. However you can imagine how it comes across to others.

We've had many conversations about situational answers but he doesn't understand why he should be forced into subterfuge (his words)when he has the facts. I'm hoping that as he gets older, he will become more willng but who knows?
