It is very hard to recognize a lie as a lie when it is told by someone who believes the lie. The best liars are those who are able to believe what they say. Even people who come off as clean-cut and honest can lie. You may be experiencing a sense of distrust around someone you have no reason to suspect is lying, Aquarius. Follow your gut feeling anyway. Is there a reason this person might want to lie? Is there a benefit? Or are you just being paranoid? This is important, so look for the truth - but do so with discretion.
