I've been a DNS for the last 18 years. My friends ask me why I continue to work in LTC when we're consistently short staffed and looked badly upon by hospital nurses. Here is why:
We have a local guy come in once a week to play the piano for the residents. He knows them all by name and knows their favorite songs. I was in the room when he started playing L. Cohen's Hallelulah.. for one of the significantly demented residents. She very rarely says anything that makes sense. I always help out with the sing a long. She mumbled through the verse until the Hallelulah chorus. She went for the low note...I hit the high ones. She took my hand, looked right at me and said "I can't do THAT!"
That, colleagues, is the reason I stay.
