Parlez, what you said about a staff member walking right by someone who is trying to get their attention was something I witnessed myself last fall when I was visiting my uncle in a nursing home. There was the most wonderful elderly couple that lived there. They were easily into their 90's. They were both in wheel chairs and the wife seemed rather unresponsive. The husband appeared to be unable to speak but was sitting upright in his chair, attending to his wife, rearranging her blanket, etc. He was a most dapper fellow with a white hat and a jacket on. An attendant walked by and he tried to signal her, you could tell it was quite an effort and she just kep walking. You could see the frustration in his face. Another man, who appeared to be a stroke victim, was sitting in his wheelchair watching the world go by when an attendant came up behind his chair to wheel him elsewhere. She walked up behind him without a word and turned his chair. It scared him to no end! She could easily have said a word to him or let him know she was there before she just jerked his chair from behind. But, having said that, I also met some of the nicest most caring people that worked there as well. It's a very tough job and I admire anyone who can do it day in and day out!
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming -
Wow! What a ride!
