Another great way to tell if you want to be in a relationship with someone is by judging how she treats others. Does she talk to waiters like a spoiled brat or is she kind and polite? Is she rude to someone trying to assist her or is she usually warm and friendly? If someone accidentally pushes her in the street, would she start an argument or stay calm?

In her book, Brilliant Psychology: How to Understand Yourself and Other People, Psychologist, Louise Deacon says that we tend to be way more harsh on other people then we are on ourselves, oftentimes finding an excuse for our own failures. Conversely, when it comes to other people, we say that any failure is their own fault.
