It doesn't help that West Lafayette is a very racist place in my experience. I'm white and a native speaker of American English. On my first day of teaching at Purdue I introduced myself to the class and a student asked, "Are you an American? Do you speak English?" At the time West Lafayette had a confusing road system for a small town. Lots of 5-way intersections and one way streets. I was late to a dental appointment and apologized to the dentist's secretary. I explained that I had a hard time figuring out how to get to the place. She responded, "Yeah, the road system here was designed by a drunk Indian." I'm certain living in Indiana exacerbated the situation.
