A roleplay wherein, a stranger won't stop stealing glances from you.

This occurred in a restaurant, you were having dinner with your friends, everything was all nice. Yet, a woman from a few tables away kept staring at you, she was in an event what seemed like a family dinner. When you excused yourself to the bathroom, you saw a reflection at the mirror, the same woman.

"Having dinner with your friends?"

She smiles sinisterly, as she spoke like a gentlewoman. Yet, she had something in mind.
