So......I went down to help out mom some.  She was able to get out of the house and not have to worry about leaving Dad.  She went shoppin and errands on Thursday and Friday.  I was amazed at her good mood and energy when she returned from her little trips.  It really does her good to get out a little and get some air.  She really appreciates any help and anyone who wants to visit.  Dad was in and out of it for the few days I was there.  Nothing really unusual that I observed except for Friday evening he was very restless.  He wouldn't sit for very long but keep getting up and opening doors and standing in front of things looking very puzzled as if he was trying to remember something.  For the most part, he was pretty mild mannered and even his sense of humor came out at times.  One time at the dinner table he burped real loud and then said "got him!"  --whatever that means.  And he did joke some with shaking and acting like he's shaking to death.  It's funny, when you're with him you go from being amused to heartbroken for him.  I just encourage everyone to try and keep in touch off and on with mom, she's pretty emotional and this is quite the trying time for her.  I know she feels the love and support from her family, and it does bouy (sp?) her up.  Thanks for everyone's help and prayers.
