When they stay home, parents usually ask them to finish their homework which usually make them feel sad. All the new problems need them try their best to figure out, it's not easy for most children. In that case, most parents still ask them repeat the same thing day after day until their feel weary of studying. The chidren definitely know the purpose of playing with friends, because they can feel happy. But for studaying, most of them don't have a clear understanding on it. They even think that they are forced to study by their teachers and parnets. Though their parents always tell them the purposes of studying hard, they are really hard to understand. The good thing is that most children like to imitate what their parents do. So, if you want your children have a great academic development, you'd rather study with them than tell them the truths.
