" Back in 'my day' – though I didn't claim ownership of it at the time, this is what used to happen: you met a girl, you were attracted to her, you tried to ingratiate yourself, you would invite her to a couple of social events – for instance the pub – and then ask her out on her own, then again, and after a goodnight kiss of variable heat, you were somehow, officially, 'going out' with her. Only when you were semi-publicly committed did you discover what her sexual policy might be. And sometimes this meant her body would be as tightly guarded as a fisheries exclusion zone. "

― Julian Barnes , The Sense of an Ending
