Third, bad friends; It's mean a friend you can't trust, belief or another think like that. Sometimes they will make you belief. In fact, they will make you to be a joke. It's bad to your feel. They're insincere for instance, you have a problem but you don't know how you do and they offer you to help that but there're not dodoing this. They just say, instigate or insult you after that. Then do you want a friend like this?
