So DS1 is in year 11. He is currently doing his mocks and has been working and revising really hard for these over the last few weeks- he's doing around 3 hours of revision on school nights and 8 hours a day at weekends. This is driven by him- although we have always emphasised to him the importance of working hard, he is very ambitious himself and wants top grades.
DS is generally really hard working and tries hard at everything he does - he also plays football and goes to the gym and puts a lot of effort into these.
Dsis also has a son in year 11 (DNephew). DNephew is bright but frankly very lazy and seems to spend most of his time on Xbox or Netflix. DNephew asked DS over at the weekend to play Xbox- DS refused as he wanted to revise.
I now have Dsis saying that DS is working too hard and I should be encouraging him to be more relaxed like Dnephew. Aibu to tell her it is none of her business and if DS wants to work hard rather than play Xbox, he is entitled to do that?
