- You have supers-sensory perception and you get a negative ‘vibe’ that tells you something is off about that person
- The person reminds you of someone you know that you don’t like (even if it you aren’t aware that the person reminds you of someone else)
- You are having a bad day or at a negative place in your own life and so, you really aren’t going to like anyone very much
- You are a judgemental person in general, so you are quick to pass judgement and/or form an opinion of someone based on superficial things like the clothes they are wearing.
(I’m not saying you personally fit any of the categories above, I’m speaking in general here.)
