A musical number about a woman’s letter to her husband on the second world war frontline unlocked my ability to blub – and made me a happier person

I am sure I must have cried as a child, but by the time I was a teenager it had stopped. It was probably a boarding school thing. Very stiff upper lip. My parents are not the most emotionally available human beings, either. I like to tease them by saying: “I love you.” You can see the panic in their eyes. They will normally say: “All right then, bye.”

My gran died when I was about 18, and I was sad, of course, but in terms of tears there was nothing, no water. I never cried at movies. I didn’t cry on my wedding day, nor at the birth of either of my daughters. It never alarmed me. I actually thought I might have underactive tear glands. Looking back, it was probably all about control.
