I suddenly feel the need to give an example... I don't want to have my attitude taken the wrong way. I'd much rather be around someone who can smile and try to make the best of things and stay positive. But here's my examples of fakeness that I hate:
A traveling nurse was stopping by every 2-4 weeks to visit my son after his surgery. She wasn't technically monitoring health per se, it was more development. Well being she was judging him against normal healthy children I felt it was unfair off the bat, but I figured it was free help so I tried to go along with it. She was very smiley and seemingly polite, but I soon realized that was anything but sweet. She picked apart everything with my son, and over and over tried to tell me I needed to do things differently, and that he was behind because he sat in his toddler chair too much, etc. Well he had surgery, he enjoyed rocking himself in his chair. I tried taking him out to play with him but he cried. I was not about to put him through any duress, and I tried to nicely explain this to her, but she just got more and more rude the more she visited until my husband hated seeing me so upset so we told her to stop coming. And I hated how when he was around she wasn't as rude to him as she was me, although she still ticked him off with her little remarks like "vacations over, yeah right". All over letting him rest in his chair. I so wanted to tell her to shove her smile where the sun don't shine.
Then there was this boss I had. She looked so super sweet with a huge smile 24/7. I soon found out differently, and was warned by alot of people within my company that she was devious and couldn't be trusted. For example, one day she had a guy working under her and she says to him "just go home we can finish up". It was Friday and he had to travel to get home because he was a merchandiser who had to stay in a motel during the week to help build one of our stores. Anyways, he says ok and goes home. She immediately pulled out her cell phone and called her boss and says "I can't believe he left us here with all this work". After she told him to leave. I just wanted to smack her!
