When you meet someone for the first time, whether you realize it or not, you’re making a first impression, and so are they. Sometimes you might be drawn in when someone is very charismatic, but other times, you might be turned off by someone’s actions.

While first impressions aren’t always accurate, sometimes they are. Sometimes, through experience, people start to understand what to look out for when they meet someone new.

Reddit users answered the question “What’s the biggest red flag when meeting new people?” The answers are enlightening. Scroll down for 13 examples of red flags when meeting someone for the first time.

  1. Tries Too Hard

    Reddit user Gleapglop wrote:

    “One of my bosses once told me that whenever you start a new job/position uts usually the first person who tries really hard to be your friend is the problem child of the office. They’ll usually start telling you of people to avoid as well. I’ve found this very very useful.”

  2. Putting Your Interests Down

  3. Not Listening

    From Reddit user Saders_1609:

  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”

  5. It’s Just a Joke!

  7. Pay Attention to Me

    “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.”
