Changes in Pronoun
If a person says I got up, took a shower, got dressed, I went and had breakfast, we left for work… that change in pronoun tells us right away that there was somebody else.
Gaps in Time
Sometimes if we asked a person what happened: I got up, took a shower, got dressed, I had breakfast, later on I left for work. The ‘later on’ is a clue for us that something happened from the time they were having breakfast to the time they left for work.
When you ask somebody a question and they give you an answer that has nothing to do with your question… they hope that just by virtue of you getting a response that you are going to move onto the next question. This type of deception can be effective if the interviewer is not listening for the responses and simply skips on.
