"Sharing is somtimes a problem and he can become sulky when reprimanded. However the episode is soon forgotten and no grudge held"
"He has a wide and varied vocabulary enabling him to express himself in an authoritative manner"
"In the sandpit, he is the architect and uses a clipboard to make notes" - why can't he just build sandcastles like the others.
There are other nice stuff about having a great imagination and enjoying role-playing with his friends.
But shouldn't the teacher find out about his moods and bossyness for herself. I know it's not a dreadful report but it does make him sound a bit obnoxious.
