I know, I know, I know, it's their wedding, they should have it however and whenever they want it. Of course they should.
But because we live 4 hours away, it's taking DS1 out of school for 2 days and 2 days holiday for DH. Of course, we will go (it's my SIL), I just wish it had been on a Saturday, or even a Friday (which would have been just one day off).
