Which Reminds Me

Ye, I vaguely remember having studied the Spanish language in depth, that in Spanish, the pronoun you can be either Usted or Tu. The usted is a more formal and chilly distant relationship, whereas the tu is used amongst friends. Yes, I suppose the tu should not be wasted on some people who obviously are not my friends. Needless to say. So I should probably just return their chilling formalities in kind, OK fine, because with friends like that I would have no need of enemies. They declared themselves to be my enemies, so, yes, get clue.
