Genuine

As I get older (and hopefully a little wiser) I find myself making revelations not only about myself and my own actions but about people around me. Sometimes I think that I am truly over analyzing things but usually I can't stop myself from observing, analyzing and concluding. One thing that I have noticed in the past few months is that many people I am now surrounded with just don't seem to be genuine. I have conversations with them which leave me wondering if they are being truthful. I often feel like people are being passive aggressive. Sometimes I outright think they are living on fantasy island (must be nice!) and other times I just feel like I need a big break from the BS. So, my question is, what do you do when you aren't sure someone is dealing you the real goods? Do you call them on it? Do you accept that perhaps they just are not genuine even to themselves or do you simply kick them to the curb?
