What the disease does

Jan spent some time over at Kami's today. She was in a good mood or so it seemed, but after about two hours she started getting into this weepy, almost angry mood. After we came home I hoped that she would take a nap, but upon suggestion, she became angry. How can I tell? Believe me, anyone could tell by the way she looked at me. We sat and watched American Idol as we have in the weeks past and went to bed about 9. She seemed fine but after tucking her into bed I noticed she had tears so I asked what the tears were for. She can't communicate so she doesn't try. I asked more questions about her hurting, did I say something wrong, what happened. She was unable to speak which I know leads to frustration on her part. After a few minutes I determined that I wasn't going to resolve the tears and maybe it would just be best to leave the room and let her get to sleep. That's really hard to do, but most of the time trying to question or reason with her only aggravates the situation.
