Reading The Wedding Group by excellent Elizabeth Taylor, and came across this chapter opener, below. I'm not the only one who worries about birds :
"'I can't think why birds don't get duodenal ulcers,' Midge said to Mrs Brindle. She was standing at one of the drawing-room windows, watching them, her birds, swooping into and away from the ham-bone on the lawn. 'It's terrible the way they have to eat their food, so full of anxiety all the time.'
'Perhaps they do get them, ulcers,' Mrs Brindle said, flicking her duster along bookshelves. 'We're hardly to know.'"
