If the plumber calls, I expect him to mend the water problem. Plus a bit of chat about the weather, or football, or the closure of the Wedhewood factory.If it's a nurse, she will, I hope, change the dressings, help me into or out of bed or whatever is required. Plus a bit of chat about etc etc. I don't really want to hear about their religious prsctises, and I won't tell them about mine.
