Pretext, text and context

Pretext, text, and context can be viewed as three kind of lenses we look through. For example, I have a female friend who is a deputy sheriff. She is of Hispanic origin (but looks Asian). When she is working out in the field, it is not uncommon for Asians to run up to her and start speaking mandarin, Vietnamese or another Asian dialect. The poor girl doesn't even know how to speak Spanish much less an Asian dialect. Her pretext would be her outside shell that can appear Asian. Her text is she is an English speaking deputy who must assist the non-English speaking citizen who needs her help. She would call for a translator and handle the situation. The context of this paradigm is that while she is on duty, she IS the Sheriff's Department. She is no longer a female Hispanic deputy sheriff. What every she does or says reflects back to all of law enforcement.
