It took me three years to read your letter. Back in 2018, when I didn’t really understand the process, I thought ‘pen sketch’ meant an artist’s drawing of the sperm donor. I didn’t look at it as I didn’t want to see you. Not then. I didn’t want to choose a donor based on looks and I didn’t want to identify a stranger on the faces of my prospective children. Later, when I joined groups for donor assisted families, I discovered – by chance when reading a Facebook post – that the so called ‘pen sketch’ was not a picture, it was a letter.
