Yes - my DS8 is like this. He recently attended a camp where there was acting. He came home and told me that his camp counselor said something that DS did NOT agree with. Apparently his counselor told him that DS was very good at acting and liked the British accent he used in his role!

Another counselor told me the same when I dropped DS off the next day.

I'm pretty sure it's a combination of not wanting the attention (that comes from praise) and perfectionism (he feels it wasn't perfect).

I have another relative who is the same way.
