Sorry- but I have to agree with Lime Slice and PumpkinZulu- I think it is a little petty for you to be this upset. It would be different if they knew what date you had planned and used that date deliberately but they just chose a date that was good for them. I don't understand why they should change it to suit you?? I don't understand the feeling that you can't have it in a month when there is anything else happening either. Sorry
