When my fiance and I split up his ex threw a party and his daughter rang me on my birthday (which was a day after she learnt we are not together) and left the phone on while she was not talking to me but to her friend and saying to her friend, with this really happy extatic voice, that this is the best day of her life and that she is so happy and she is going out to celebrate.

I can never understand this sort of mean thinking. There is always an element of judgemental convinction in that and I think we will all be better off focusing on ourselves. Our own happiness. Making ourselves better and content within ourselves. I feel sorry for this girl. My sad day was the happiest day of her life.
