What is something you've come to realise just doesn't work for you?

There is someone who related to me via marriage. She is so obsessive, unreasonable and whatever you can think off to piss you off, she has it all!So, I had made the first move.. to apologised for the blame which is not mine... just do it for the sake of the person I love. My sister will invite her to functions, bought for her material items whatever she loves, whatever she dictates... It came to no avail...it is overboard, she thinks that the whole world owes her.... Ridiculous!20 years has past, she never mellows and she became worse...given in to her way too MUCH! I ignore her, I realised it just doesn't WORK. Only God and miracle can change her...all the best, live life to the fullest! One thing I learned is : [b]You can't pleased everyone... therefore might as well pleased yourself![/b]
