Found 2 birthday cards Michael sent mom one month before his death. One was signed "Have a Nice Day" and the other signed "Merry Birthday". Now I know, both were real clues as to what was going on with him.
He was saying very little at this time and mostly would repeat "Have a Nice Day".
Then for him to say Merry Birthday instead of Happy Birthday.....was out of context for him.
His handwriting was changing as well. Patsy's handwriting changed drastically as well. I noticed her handwriting changed about 7 years before her death. Michael's didn't change until about a year before his death.
