I'm talking with this chick at a bus stop. Opened with my standard...
'do you ever get hit on a bus stop?' , followed with
'how often?' , 'do you like it?' ,
'what do they usually say?' (to set myself apart) and
'do you know what kind of an impression you make on guys?' (curiosity).
Of course, this is not 20 questions, but my comment on her answer leads to the next question, that is, I managed to pull it off this time.
