One GOOD thing about Spanish is that you can immediately set the tone of the conversation by talking down to a person just by using the informal pronoun and verb conjugations. Or flatter them by using the formal polite forms.
"Tu" (for "you") is used informally among friends and family, as well as when talking down to younger people and those who rank lower socially.
"Usted" (for "you") is used in polite, impersonal conversation, such as in business, or when talking to someone of higher social status, regardless of age.
As things are, a lot of the illegal invaders do not even KNOW the formal verb conjugations, and thus cannot properly talk to us. If someone like that addresses me improperly in the informal, I puff up and announce (in Spanish) "I learned formal Spanish in University, and you are going to need a translator".
I learned this as a social worker, and I imagine it would apply to many situations.
Also Spanish is full of extremely hard-hitting insults and profanity. I am VERY proud of my Mexican slang nickname: La guerinche chocante (the stuck up blonde bitch)
