HOW DID PATRIC DO H.W ????

The elf told Patrick that he would be doing all his homework. However, he did not have knowledge of any subject. So, he kept coaxing Patrick to bring him books from the library, search for and read out word meanings from the dictionary and explain time tables to him. This is how it only seemed to Patrick that the elf was doing the homework although he was the person who had actually done it all.
