fun at school

When I picked G up from preschool today, he looked happy.  He even said "bye" to his class.  So I thought I'd ask him that question I've asked so many times before with no luck.  "Did you have fun at school?"  And this time, he answered.  "I had fun at school."  Yay!  It wasn't unique, and it was definitely modeled after my question, but he answered in the first person and said every word of the sentence and the little smile on his face told me that he understood what he was telling me.  I am so proud of his progress!
