So we are planning our wedding and a date that we liked linked into my parents anniversary the following day which I thought was a lovely thing, not really thinking that it would be their 40th anniversary next year. When I told them the day we had planned it was suddenly a big issue that they were planning getting the family together to celebrate their day. Am I being unfair expecting them to move their celebrations to either the week before or the week after? I don't know what to do and feel awful about the whole thing. Any advice would be great.
