Regarding only likeing lunch and recess:
He said that "I'm born and then I die, nothing ever happens in my life."

This is from a kid who plays 2 instruments (piano and violin), plays hockey, is kept busy over weekends (because he does not do it himself), goes on many outings, has many playdates, etc.

It's just not enough. There is really not enough hours in the day. I have tried scaling back, thinking he was maybe kept to busy, but it just made him (and all around him) miserable.

In regards to participating in class:
We have encouraged him to participate in class more, but he told me that the teacher stops him "always" from saying what he wants to say, telling him that he will confuse the other kids. An example of this will be when the teacher told them that there are 3 states of matter, and he then, respectfully, disagreed. Also when he wanted to solve a math problem like 13 + 13 = 26 is the same as 13 x 2 = 26
