Decline

As I continued to visit, my father declined more at each visit. 

He was put on an oxygen feed. 

He was shifted from the walker to a wheelchair. 

There was dramatic visit where he was very shaky and seemed discombobulated by his situation. He would remove his oxygen nose tubes, look at them and then put them back every minute or so. He seemed to be looking around trying to determine where he was. Thankfully there were other less concerning visits. 

My mom seemed mostly oblivious of his decline. I did tell her at some point that we had learned he had cancer. She seemed briefly paused by the information, but not dramatically upset.
