I don't think this is so strange. Some days are a blur for me--if I were missing a child, it would take me a little while to organize my thoughts and memory. The problem I have with comments like this from DY is that we don't know the context of the situation--if this was the afternoon/evening of Kyron's disappearance, TH may have needed time to calm down and remember her day. If it was days later, after she'd had time to remember, I would wonder. (And, DY doesn't clarify--is this comment is related to the LDT? I wonder!) I think this shows, in another instance, how two people can have different actions/reactions to stress. Desiree remembered an inconsequential detail--good for her, but that doesn't make TH guilty...
