It has been thought that we should trust our first impression when we meet people for the first time.
In my opinion, the first impression is playing a big role to determine our relation with that person in the future, it is something happening subconsciously that we can’t control. However, we shouldn’t depend on that, we can’t judge person from first time we meet, as there is a possibility that person had a bad day or going through a problem that could be a reason we got a bad impression of him/her. We should give time to decide if someone is good or not.
Moreover, the situations are the best way to evaluate someone. Only good friends will appear and stand by our side in bad situations. hanging out, laughing and meeting in parties doesn’t mean at all those people are friends to us. There are other indicators which only time can tell, such as having a good conversations, they are getting happy for you when something good happens to you, they are supportive to your decisions and they are not getting jealous about your success. All these indicators that mentioned above can tell us more about the personality and, only time can prove that, which makes first time just a temporary feeling and without any doubt time can change it.
To sum up, first time indicator can play an important role in our relation with someone, although it is not enough to decide whether the person has a good personality or not, real life situations will tell us more.
