Verbal Habits of Deceptive People - Verbal Leaks 5: Pronoun Inaccuracies / Inconsistencies. Pronouns that makes a statement personal, as with distancing statements, are often absent in a liar's statement; e.g. "Got up this morning. Went for a run, took a shower and changed. Got to work. Did not even stop to check e-mails." Another way someone might distance themselves through language while answering questions they find threatening is by replacing the pronoun "I" with "you". E.g. "You just don't do that kind of thing," or "You would not want to walk there at night."
