Your stalker

Make up your own story. This woman is your stalker. She is obsessed with you and thinks it's fun to scare you and follows you everywhere whether it's your social media, your workplace, your personal life, holidays or whatever. She never physically approaches too closely so that she can get away with her creepy activities. She often does things to you while remaining unseen. She makes it impossible for you to gather evidence against her. Watch out wherever you are, she might be watching you.
