Indicative…

A scrupulously proper use of prepositions––never at the end of a sentence!––reveals that the speaker/writer suffers from severe emotional inadequacy. An improper use of prepositions, by contrast, nearly always means the writer/speaker is schizophrenic, and to a degree proportional to his or her misuse of said prepositions. Those are the people for whom I'm writing and that's what those behaviors are indicative of.
