Halloween costume

If I ever had doubts about my youngest son's self confidence, those fears were erased recently.  We received a catalog in the mail with Halloween costumes.  CT spent a lot of time looking at the costumes, debating the merits of one over the other.  After a while, he asked me what costume I wanted him to get.  I had positively no desire to debate Ben 10 versus Spider Man versus a Ninja.  So I just told him "Why don't you dress up as a super smart 4th grader for Halloween?"  He replied, dead serious, without laughing or cracking a smile...."So you don't want me to get a costume?"  That's one confident kid.
