difficult child worked with PCA on school work until really late. At one point, difficult child took a break and took a shower. I sat down and was talking with PCA and she asked me if I knew that difficult child has some Obsessive Compulsive Disorder (OCD). My response? No way. I mean, I know easy child has some Obsessive Compulsive Disorder (OCD) quirks - nothing that negatively impacts his life...just quirky...and kinda funny. But, I've never seen it in difficult child. PCA then took the cap off a pen and set them both down on the table and said, "Wait until she comes back in." Apparently, difficult child can't stand to have things that are out of place or not closed. Again, I said, "No way! Have you seen her room???" She insisted. So, I also opened up difficult child's phone, unclipped the barrette that was on the table and took the cover off her calculator. Sure enough, first thing difficult child noticed when she walked in the room is that her phone was open and she went right over and closed it. PCA and I didn't say anything. PCA went on with the school work and difficult child reached over and put the cap back on the pen, then immediately picked up the barrette to fasten it. At that point, difficult child was onto us and she was able to laugh with us. I was just so shocked. I have never noticed that in her. Obviously, it's just quirky Obsessive Compulsive Disorder (OCD) stuff and we all have it to some extent. But, it was distracting enough that she couldn't do her school work until it was done. Interesting.
