Six Sentences

My attempt at a six sentence story:

She was a vision to behold. I sat opposite her during a one hour train journey, and she kept smiling at me. Nervous, I thought, or a foreigner in a foreign land.

I gathered up my stuff and blurted out, "This is my stop", and she retorted, "Too bad!".

What did she mean?!
