This from Tom Reynolds :
The staff don't say anything, but I get the distinct impression that they have been getting tired of this patient being awake while they are at work. If all your patients are sleeping then the night shift has little to do. If this patient has been awake, then they actually have to talk to him. In a lot of the nursing homes that I've been to the nursing staff don't like talking to the patients.
In a fair few nursing homes that I've been to the staff and the patients rarely share a language, and so everyone just 'gives up'.
