@selvtillit is stalking someone...
How observant was she to be able to notice such a strange character, following her from a distance! For a time Erika ignored the presence completely, going about her business as she walked up and down the busy street looking for her hobby shop.
It occurred to her then... What if this guy was dangerous? What if he found out where she liked to shop and he ended up meeting her there later, with the intention of kidnapping her and using her for strange, sordid experiments! She’d heard plenty of stories of kidnappings in the area, one of which affected her friend circle directly.
Erika walked casually down the street, bypassing her favorite store completely. It was probably best to avoid it just for now, and think of a plan...
She slowed her pace, looking around the area and smiling at the other passersby. She did her absolute best not to make it known that she was aware of being watched, until she came to the corner of a street at a red light...
Suddenly she whirled, pointing her finger in the direction of her strange, tall, stalker figure poking up in the somewhat near distance -- “YOU! IF YOU’RE A CREEPY STALKER YOU BETTER BELIEVE I’M GONNA GET YOU!”
