I once talked to a girl. I aided as a translator for two french turists that asked her for directions. Since she didn`t knew french, I served as her spokesman. In the end, after the turists left, she sat besides me at the bus stop. She asked if she called me sir or you.
Said that the choices was hers and we talked for while. She never asked my name nor I saked her name. We bid farewell and never saw each other again. Just a normal day in the city.
