I have 2 DC currently yr 6 and yr 7. My niece in NZ (where I am from) is getting married in November. We weren't going to go as apart from anything else we cant afford it. My mum rang yesterday and offered to pay for the fares (which is the main cost since we would stay with family whilst we were there) as she really wants the whole family to be there. This is a lot of money for her but she really would like us there and is quite elderly and says this might be the last family wedding she goes to (though I certainly hope she is wrong about that).
It is a big family occasion and we don't really have that many family occasions - last one was 8 years ago. The whole family are close and all live very close to each other etc so even though it is my niece, it does seem to me to be someone in my close family if you see what I mean, although to be fair I don't see/talk to her much these days as I live over here and she has a busy life and not much interested in her auntie in England. But I still really would feel I was missing something big on my side of the family.
DH just doesn't want to consider it as he thinks it simply isn't possible to take the DC out of school - they would be in year 7 and year 8 and I think we would have to take them out for 2 weeks in November. We would need to get there in time to get over the worst of the jet lag, and having spent that much on the trip I think we would have to stay that amount of time to see my mum etc.
I honestly don't know if IABU. I haven't even asked the school as DH is so set against it.
