Your Stalker

you see a girl behind you. In fact, you see her regularly. You are sure she follows you pretty much every day for some reason. She looks very normal, but she is a cutie. She wears a face mask. The fact that she came within five meters of you is not just weird, but frightening.
She increases her walking pace, and so do you, so the distance is the same. You're pretty sure she wants to get close, and it's scary. Then you stumble a bit, just enough for her to close the distance.
