When I was single in my late 30s, I went through a spate of online dating. I signed up to the relevant apps. I chose profile photos that were flattering yet approachable. I pretended I had hobbies. I completed the biographical Q&As in what I hoped was a witty manner, despite the increasingly esoteric nature of the questions. ‘What’s the most spontaneous thing you’ve ever done?’ was one of them. I agonised over it for several minutes before scheduling an answer some time in late 2019.
