What do you think of thi first few paragraphs of my story?

Not bad, but it makes me wonder what the surroundings are that makes it a contrast. Also, what's she thinking if it's so important. How can she tell he's tall if he's behind the wheel of a cab? *editing to change/then why does he ask where she's headed and not what she's doing there?* It's interesting but could use some detail. A little more wouldn't give the story away yet. Good luck.
