• The United States is a righteous, fair, and just country.
• Success and a comfortable life necessarily followed hard, diligent, smart work
• Adults, by virtue of having been around longer, necessarily knew more and knew better than I.

weed smokers with the image of typical drug users

anything religiouse (though even in second grade i unironicly said “i belief only in facts and science. Mrs Teacher, is there a religion that is about the facts of science?” Yeaaah the autism has always been strong)

I thought cities were all walled.I lived in a city surround by a wall, and played Civilization 2 where towns would have walls.I was so confused when we traveled to next town and it just sprawled everywhere
