It wasn't stated in the invitation it was a water fight party!
My son was so upset that only 2 children had a watergun and he didn't! There were arguments all day over who would have the next go of the 2nd water gun and all the girls did was scream whilst trying to avoid the water!
The mother of the birthday boy looked visably distressed!
I know lot of the girls had lovely dresses on and I wouldn't have been happy if my daughter came home soaked, I'm sure if they had known water was going to be involved they would have gone for 'play clothes' rather than party best.
