Kenny is annoying, has little respect for Armando and Mexican culture and is extremely untouched by all the other cultures around him in Florida. But I have had acquaintances just as under-exposed.
In college, in California which has innumerable clusters of different cultures, religions, restaurants, events, etc... she was so overwhelmed by how easy it was to work on our project together that she apologized to me for being “the only Black friend I have ever had. Also the only Black person I have ever known personally.” She was not a fresh eyed freshman but in her thirties somewhat.
There are communities where houses cannot be sold to anyone outside of the families who originally live there. They are just regular houses of your white picket fence variety, not sprawling estates. They are white communities and maybe a sprinkling of Mexican families... So, even in the 21st century, it is easy to be underexposed.
