Cassidy Reese uses informal and formal English depending on the situation and audience. Informal English is used with friends and family, using simplified language and puns when texting her sister about wedding dresses. Formal English is used with strangers, professors, and older generations, speaking politely using terms like "ma'am" and "thank you" when asking a AAA operator for help after locking her keys in her car. As people age, they learn there are different versions of English and appropriate contexts for each.
