If I were in Helen's position and very stressed, and all I was offered during these intensive interviews was a misereable cup of cold water I would not be very forthcoming with my story.
I am quite serious about this. A warm comforting drink would make most people feel a lot better in a situation like this than offering a glass of cold water.
It's what people did in wartime if bombed out or other disaster, people offered a person something warm and comforting to drink, is a bit of basic kindness and simple cherishing that can make people feel a whole lot better. Anna Tregorran take note.
