4. Can’t Keep Friends

   From NotoriousMFT:

   “usually when people speak of having a lot of people in their life that somehow turned on them and now they don’t speak anymore. i remember one old coworker would become super fast friends with someone, then within weeks “yeah we dont really talk anymore” once, ill accept, hell even twice, but when its 4-5 times over…. guess what, its not everyone else”

7. Pay Attention to Me

    From londone11:

    “I have only ever met 2 men (that I’m aware of) who lied to me about their ages when we met. Both of these men turned out to be extremely unpleasant and abusive people (I dated one of them and knew the gf of the other one). I think people who lie easily even over trivial things tend to have very complex psychological problems and are best steered clear of.”
