Shut the F@#k up!

Okay, and with that overly dramatic title you're probably wondering what the hell I'm getting ready to write about. Well, people. I deal with people all day-customers, doctors, nurses, practitioners, insurance companies, co-workers, medical staff, etc. The thing I am running into is how to keep my mouth shut while still staying true to myself. See, I am really good at being a yes-man on the phone and a lot of times in person. I am agreeable with the people I deal with all day at my job, but that, I have been finding out, is just a way to keep up an unhealthy practice that does not allow me to say what I think/feel/want, etc.
Like take today for example. I got a call from two higher ups about a patient who was upset with me and said I was a liar. Now, the last time I was blatantly called a liar by someone who was not a family member or friend, I had an asshole professor in college tell me I lied about turning in a paper-which, by the way, I did NOT lie about! I turned the damn thing in-I can't help it if he was a completely scatterbrained pig of a teacher. ugh. (ps-I ended up getting a B in his class all because of that "missing" paper-surprised he didn't turn me in to the term paper Nazis.)
Anyway, this person who said I lied about something had only one week ago, gone on a tirade(via phone) about how we live in a socialist society, that giving tax money to help people in need was wrong and that all people who couldn't make as much money as he could should basically rid the world of their personage. Now, the polite, tactful, customer service oriented Erin just sort of laughed it off and steered the person back to the task at hand, whatever it happened to be at the time. The real me wanted to tell him that he was speaking in an offensive manner and that I would rather be a socialist, bleeding heart liberal than a capitalistic asshole!
Whatever. Point is, when you get me on the phone at work I will be as genteel as a belle, but please do not expect to get my real thoughts on issues while at work.
Oh misguided patients who think my main goal in life is to smile and nod at them.
Wake up!
