Briefly - I am 40 on Saturday. We get back from holiday the day after my birthday. My mum (who lives near us) originally invited us to lunch on the sunday as it will be my "birthdya weekend". NOw she has told me she is going to visit her sister in Devon and wont be able to see me on sunday. I feel quite snubbed by this. she isnt close to her sister (only became aware of her existence 2 years ago, her sister has been in an institution all her life and wont recognise my mother when she sees her). I think as it is my 40th, I should take priority here especially as I did all the organising for my mums 70th birthday a few weeks ago (cake, champagne, restaurant etc, I did it all). Am I right to be upset here?
