Do you know what I am talking about when I say people acting fake? I see this all the time. Normally, it's when a person I have rarely met before acts like they are your best friend or like they have known you for your whole life. They're the people that give you the big hug or smile and you're just kind of like... "okay."
When this happens to me, I automatically note it and don't really want to be around the person because they aren't being their self. They are being whatever (or, whoever) they perceive that another person wants them to be. It's like Regina George in that scene in "Mean Girls" when she tells the girl she loves her skirt, and then as soon as the girl walks away, she turns around and says she hates it.
And maybe all people who act really nice to you generally are the really nice people. But others–not so much. They put on the facade when, in reality, they don't like you, and this is what really frustrates me. If you don't like me, don't act like you do. I feel like I see this all the time. And honestly, it gives me anxiety. Anxiety in the sense that I have to constantly ask myself: What does that person, or any person around me, actually think? If that one person is being fake, how do I know if everyone else is being fake or genuine?
I guess what I'm saying is that you don't have to like everyone–people clash and it's OK. Just don't act like you like them to their face and then have a different opinion behind their back. Just be real and be yourself.
