Charles has a very compartmentalized mind. The other day, the morning after Mom had left for a trip, Charles asked me where Mom was. I started to explain that she had left on a trip when Charles interrupts and lays out Mom’s entire itenary for me, where she went, how long she would be gone (“two days and one night!”), what she would doing, etc. Apparently Charles had paid attention when Mom explained it to him, but didn’t connect it with an explanation of why Mom wasn’t around.
