Hi Hoony,

I'm happy that you did not forget to do your homework. It seems that you know what those people above do, good job! However, please study the corrections that I made. You still have to be careful of your usage of prepositions and subject verb agreement. Overall, keep on studying our lessons! Merry Christmas, Hoony!
