I have a few tips! OK, try to stimulate his academic interests; try to give him enough neurological stimulation to feed his intellectual needs. Treat him like you would treat an adult (if he wants to be treated like one, at least), but don't expect him to be mature 24/7. Believe me, even though I'm a gifted person, I still have emotional outbursts and I'm just as (or maybe a little less) self-concious as any person of the awkward phase!

I hope this helps!
