Answer:
Based on the picture and what the mother said to her son is a sign that the mother was tired of her son. Tired of always reminding him that he should study. The mother was irritated of her son because he chose to play computer games and watching TV than studying for his lessons. That's why the mother said to her son in a sarcastic way that if he don't want to study, then he can play all long day he want. No more studying.
Maybe the mother said this to her son because her son might be hard-headed to the point that he chose to play than to study his modules. Well then, this is what a typical mother would do, saying to their children that he/she could do that, but the thing is , it is a reverse way.
