Liar
It can be tough trying to go through life without lying. Everyone does it now and again, to get themselves out of a situation or just to make someone feel better about themselves. For example, telling someone they haven’t gained weight or that their outfit looks fantastic, you know, little white lies.
Those types of lies never really hurt anyone in the long term, so we will let them go. But when you want to catch someone lying, usually the best way is to see their reaction when you call them a liar. If they get super defensive, it’s a sure sign that you caught them red-handed.
