So yesterday we had a get-together with our NCT group - kids were mostly aged 7 and a bit but there was a 6.5yo and a baby there as well. We all get on well, usually, as do the DC.
The thing: the 6.5yo got squirted in the head during a game/fight with the hose. One of the bigger kids was wielding it. 6.5yo was furious/upset and demanded a chance to settle the score. Bigger kid wouldn't let 6.5yo get him - kept dancing away just out of range and laughing. 6.5yo couldn't cope with the perceived unfairness of this and got very upset. Mother of the 6.5yo thinks bigger kid should have let himself get squirted, to balance the scores, and then all would have been fine. Mother of the bigger kid thinks he was perfectly in his rights to dodge getting squirted and 6.5yo should have just dealt with it. All parties were very polite about it though 
Just out of interest (because it was clearly a source of disagreement!), who, if anyone, was BU?
