Well, one story could be that a girl I knew from school started showing up everywhere I went. She'd be at the coffee shop I frequented, the park where I jogged, and even at the library where I studied. It was really creepy at first. But later I found out she just wanted to be friends and didn't know how to approach me in a normal way.
Well, here's a stalking short story idea. There's a detective who is investigating a case of a woman being stalked. The stalker leaves strange notes and gifts at her doorstep. As the detective digs deeper, he discovers that the stalker is someone from the woman's past who has a twisted obsession with her. Another story could be that a famous singer is stalked by a person who hacks into their social media accounts to find out their whereabouts. In a third story, a neighbor starts stalking another neighbor just because they have a nice garden and the stalker becomes obsessed with having a similar one.
