The last two lines of the poem are not prohibitions or instructions. What is the adult now asking the child to do? Do you think the poet is suggesting that this is unreasonable? Why?
In the last two lines of the poem, the adult is asking the child if he cannot make up his own mind about anything. The poet is suggesting that this is unreasonable because on the one hand the adult gives the child all sorts of instructions through constant nagging and on the other hand, the adult asks him to make up his own mind. The two actions are contradictory. All the child’s actions on which he gets instructions from the adult to not to do it that way are actually from his own mind. That is what he thinks and therefore, does. However, the adults do not find those actions appropriate and hence, instruct him to do certain things in a certain way. The poet is suggesting that if the adults find the child’s actions, which are a result of his thinking in his mind, incorrect, then they should not ask him if he cannot make up his own mind about anything. Or if this is what they want, then they should stop instructing and correcting him.
