every night, when I put my boys to bed, I say “Schlaf gut”. Every night, when I say that, I think of when I was young in school in Germany and I used to say it to myself.. There are so many things that when you don’t want to remember them you just block out of your mind but then you can’t explain why phrases stick in your memory and are important to you beyond words. “Schlaf gut” is one of those phrases to me. I don’t remember my mum ever saying it to me. Don’t get me wrong, she was brilliant, I had a happy childhood, but I don’t remember her ever saying that to me. So why do I say to my boys? Who knows? Anyway, it doesn’t matter, the important thing is that I do say it to them.
