Grumpy old cuss

My dad called me the other day from his apartment. He has been struggling with pneumonia for the past month and has recently been put on the drug prednizone which is causing some very nasty but common side effects one of which being mood swings. I talked to my mother directly after this last conversation with him and described it to her. She spoke of a recent call that had gone the same way and that she got so frustrated with him that she suggested that he get a good colon cleanse and maybe he would feel or act so crappy towards people.
