fake over the top fakness

have you ever know someone that is soooo fake you can tell and dont want to be around them. The whole "scream" in happiness when they see you like they missed you so much and are so happy that you are there and made over how wonderful you look, sound, cute, blah blah blah....you know, the aunt that pinches your cheeks. But you know that as soon as you are gone they will erase the smiles and laughter and tell anyone that will listen how....bad, terrible, dirty, ugly, not nice, mean, ect.... you were. Well she had an Aunt like that and she was like that. I had to listen to all of it before during and after. i told myself i would never be fake would never dramatize or exaggerate my feelings. I am who i am and if you dont like me as me thats ok, but i refuse to act fake.
