P.S. It is also probably worth noting that H is likely disposed to feel like he is being treated like a child because of the way his parents treat him -- he may well be oversensitized to it to some degreee.
For instance, I am oversensitive to not having my desires taken into account because of the way I grew up. My point is that even if you always treat him like an adult, he needs to work on himself too for him to feel like he is being treated like an adult.
