 Building real and authentic friendships are always hard. Have you ever wondered if you have fake or toxic friends? Here are four harmful traits to look out for. Number one, they live to put you down. If anything, they like it when you're miserable. Number two, they like to exclude you. They tend to ditch you last minute and exclude you in future plans. Number three, they only need you when it's convenient. In other words, they use you for their own benefits. And number four, they fail at keeping promises, which means the words are way louder than their actions. So, do you have any toxic and fake friends in your life?
