you need brain

A student and I were sitting at the table working on story retell and correct question formats.  He noticed that I was rubbing my arms to keep myself warm and he looked at me and said, “You have a sweatshirt”?  I replied, “You can ask, ‘Do you have a sweatshirt’?”  He promptly repeated the question with the correct form and I answered, “No!  I don’t have a sweatshirt today.  I forgot it at home”.  To which he asked, “you bring a jacket”?  Again, I replied, “You can ask, ‘Did you bring a jacket with you”?  He quickly asked, “Did you bring a jacket”? To which again I replied, “No!  I forgot that at home too”.  To which his response was, “You need brain”! J
