She walked towards the entrance of his house and then paused at the door. She felt like it was odd to just leave and that they would possibly not see each other again. She had a interesting day and she thought it wouldn't hurt to become friends with him. Turning around she noticed him still lingering on the stairs. 

"Do you have a phone?" She asked him from downstairs, "We should keep in touch, today was...interesting." She saw a napkin on the table and a pen near another counter. Grabbing the pen, she scribbled her numbers on it. "I'll leave it here," she said as she placed the napkin on the counter and walked out the door.
