-Because their lives are pathetic. -Because they have nothing better to do. -Because they are jealous. -Because people like to feel like they have control. i.e. making people cry, hurting peoples feelings, trying to belittle people. I think that covers a lot of it. My family is TOTALLY two faced. Half don’t talk to the other half, some others don’t talk to certain ones. It’s a big ball of fire being around my family. You just have to not let yourself stoop to their level. Say your aunt is talking shit about your mom, or grandma. Just tell them you don’t want to hear it. Or just nod. Don’t take it any further, and don’t, I repeat, don’t add fuel to the fire.
