Divine Teachers and devoted students

Another PTM, and almost the only piece of feedback that Ads' class teacher gave me was that he has been making a lot of friends in class, is more outgoing and has in fact even become a little naughty after observing all the other monsters in the class :) I thought it would be unseemly to paste a smile of absolute delight on my face, but the fact is I was inwardly full of glee. My son? Naughty?? A word I have been wanting to hear for years!!!! 

At the same time, I hope the adorable naughtiness does not turn into brattiness, since there's only a fine line separating the two. Already I see him bothering his little sis a lot more than he used to, and I've had to speak to him very sternly about this kind of behaviour, a couple of times.

I also spoke to the teacher about a very annoying 'model student'-like habit of Ads. He is obsessed about homework!! He is a perfectionist when it comes to doing schoolwork well and correctly, be it writing his name and the date/subject, or drawing lines, or writing. Every piece of homework must be done as soon as he gets back from school, and I really mean as soon. He gets home, puts away his stuff, washes his hands and is all set with his books. Knowing fully well he must be very hungry, I suggest that he drinks up his milk first, maybe play a little, relax a little, even (gasp!) take a nap, and then start on his homework...but NO! It has to be done right then and there! He makes a small mistake, gets enraged while correcting it, cannot admit to me that he's really hungry and tired because he just said he wasn't....and so works himself up into a raging tantrum  ! Now I've reached the point where I ask him whether the homework is mandatory or optional! There have been many times when he mentions an assignment that I can find neither in his almanac, nor in the school intranet (where the assignments are electronically delivered to parents). When I ask him pointedly whether he really has to do it, he explains long-windedly that the concerned teacher has asked them to practice doing that thing, or said "If you like, you can ...". In other words, strictly optional! But of course the Divine Teacher has mentioned it so it must be done :(
I used to be a super-conscientious student, so I willingly take the blame here, but it is annoying. Ads teacher laughed and said "You should be happy to have a kid who stresses over homework. Mine just sit around with an xbox/ipad all day."
Yeah. We'll see how conscientious he is when he is in high school. Murphy's Law and all, right?
