"Have a drink on me. You are a credit to your generation. Polite and teaching the little boy good manners. Have a lovely evening. PS I have a daughter your age, someone did the same for her once. Hope when she has children she is as good a mother as you.'
When Sammie Welch moved her 3 year old son on her lap to let a stranger sit next to her on the train, she never expected him to leave her such a kind letter and a 5 pound note. Is it concerning that what should be normal polite behaviour now needs special thanks? Are good manners rare where you live?
