This one, Claire has explained, doesn't mean that I have to produce a technically accurate diagram of a heart. As a male, that would suit me, and I also have the necessary knowledge via my brother-in-law, who is an amateur medical researcher and bogus doctor (it was from him that I learned that the head bone is connected to the brain bone). In fact I have to draw a map showing the people, places and things in the space they occupy in my heart, with the closest ones having a big area in the middle. It was Lola's idea to have make this a challenge – she did one of these herself.
It's a change of direction, forcing me to explore inwards rather than into new corners of the world. I won't be showing it to any relatives beyond my immediate family, however, as aunts and uncles are still arguing about who sat where at our wedding.
