One day my friend was walking down the street and he saw a suspicious guy with a very aggressive behavior which attracked fear to him
Suddenly the guy walks close to him and he start's to panic as if the suspicious guy is about to attempt offensive actions all based on his face impressions and look
unfortunately the specious looking guy just walking by him and does nothing at all and my friend realizes he is just having a bad day. This is based on a true story which is a real life example of judging someone based on their look and behavior.
