Dear Sarah,
You asked me to write down my story, and I have been thinking about where to begin. I suppose it starts with your grandmother, in that small kitchen in Croydon where everything smelled of bread and furniture polish.
She used to say that life was just one long conversation, and the trick was knowing when to listen. I did not understand that until I had you. Suddenly I was the one doing all the talking, and you were the one teaching me to pay attention.
I remember the summer you turned seven. We went to Cornwall, just the two of us, because your father was working and I wanted you to see the sea properly. You stood at the edge of the water and told me you were going to be a marine biologist. You were so certain. I think that was the moment I realised you were going to be braver than me.
There are things I never told you. How scared I was when you were born. How I used to watch you sleep and worry about everything that could go wrong. How proud I was the day you stood up to that teacher who said you would never be good at maths. You proved her wrong. You have been proving people wrong your whole life.
Your grandmother would have loved the woman you have become. She always said the best people are the ones who keep asking questions. You never stopped asking. That is why I wanted to answer them all, here, in my own words, so you would have something to keep.
I am not very good at saying these things out loud. But I want you to know: you are the best thing I ever did. Everything else was just practice.
With all my love,
Mum
