Shes behind you.

She stalking you. She's been stalking you for months. She's a very beautiful girl. Every time someone is mean or hateful to you, something mysterious happens to them. Not anything serious like murder, but it makes you feel loved, as you've already connected the dots and know that she's doing it.

Today, you suddenly run into her. She seems surprised, so you know that she didn't intend to get this close to you. What do you say?
