Many people in this world has double face. Many of them pretend to be something they are not. Recently I met such individual and it feels so awkward when we see someone trying to be something they are not. This kind of people can be a good source of entertainment too but mostly dangerous.
Whenever I meet different kind of people with different kind of personality and things that I don't like among them, I try to ask myself to be clear if the thing exist in my personality or not. Thankfully I don't pretend something I'm not.
A person with simplicity and natural appearance is more impressive than trying to express oneself really very updated or advance. If you are advance and updated that will be discovered by others you meet, no need to express too much that you represent yourself like something you are absolutely not.
For example, a lady has runny nose and she continuously saying ohh sht, oh sht when this kind of expression is absolutely unnecessary and she just trying to express her smartness, this is not the end! when she wipes her nose with tissue paper she thrown all used tissues beside the bin not inside the bin. She messed the room with used tissue paper where people says prayers. What the use of that smartness showing off when they doesn’t have manner of cleanliness? I wonder because these people pretend to be concern about cleanliness but when they are absolutely not. If you clean your runny rose that's good but you can throw used tissues randomly and make the room messy.
So if you are smart, express it with your activities not with your words, sound that make others laugh. This kind of people knock others to be polite but they make sound like an elephant LOL. Always be natural and that will be accepted by everyone around you. People who mostly pretend to be something else, they are actually fake or masked. They could be dangerous too because this kind of people thinks they are right and others are wrong. Just talking about this topic because I've experienced having such people around me and thankfully they were temporary people.
