Opening lines are like titles. I am going to briefly discuss titles. This might help you, or will maybe interest any students you might attempt to shepherd/lose. I’ve found students often go no-title, and I am against no-title, unless you have been writing for 20 years and work in minimalist miniature black and white photos. Or do heroin.
