Appalled at hypocrisy

Today is yet another farewell held for a former boss. It was very strange that while everyone in that room actually disliked her and was relieved to see her go people made a show of "missing" her so much so that it became quite appalling to me. Because I know exactly what these people are saying behind her back. I don't understand that kind of hypocrisy. It makes me realize how little I know people. I understand that for the sake of decorum it s ok to hold a farewell party but to go overboard and gush how much you love and miss her is kinda sickening. It is so insincere!!!
