While coding can definitely turn into a career, it's a rather tenuous link between custom designed calc languages and "real" programming, which is often vastly different. Also, you're assuming Rayquaza's dad is rational. As much as I hate to admit it, that's quite often a bad assumption to make. Thirdly, Rayquaza's dad is his legal guardian. That means that he can legally force Rayquaza to do pretty much whatever he wants. Going over to his house, being a stranger he's never met before and thus has little to no influence, and telling him that his parenting is faulty...? If he's like the majority of parents out there, he's probably going to be at least annoyed. It may even reflect badly on Rayquaza, leading to further restrictions of his privileges. Let Rayquaza handle it, since he has the advantage of influence over his father.

Rayquaza, if it's not too personal, could you tell us exactly why he's doing this to you?  If I knew specifically why, I could help more so, since my dad did this to me multiple times before and I know a way to counter every reason they through at you (now my dad knows he'll lose so he encourages me to do a little programming each day, like maybe hour -- but got good at sneaking so I get in like 6 total)
