Standard linguistic rules

Refer to Chapter 6 of Looking Out, Looking In and answer the following:

Think of a time when you spoke with someone whose speech violated the syntactic rules that you are used to.
Explain the scenario and the situation.
Identify what you thought about that person. What was your first impression?
How was your impression of that person influenced because he or she did not follow standard linguistic rules?
Think about it in hindsight. Was this first impression valid? Why or why not?
