RCD

Reading comprehension disorder. Most people with a reading comprehension problem also have a listening comprehension disorder and a general comprehension disorder; in other words, an information-processing intellectual disorder. In simple terms, they don't brain good. This does not apply to dyslexic people, who simply aren't adept at making out words on paper but can understand concepts that they manage to read, or things that people say to them.

I think Bob has RCD. I gave him this instruction manual for these Legos and he thought the Lego went into the light socket because it had three holes.
