End of term last week and there was a class beach party (we live on the coast). Me and DS arrived and the kids already there had a variety of water-shooting devices which they were firing at one another, including a couple of super soakers. Tacit rule seemed to be to soak one another (they're all in swimwear) but not the adults who were sitting outside one parent's beach hut, fully clothed, drinking tea.
DS then decided to go to play in the sea with his body board which was quite a distance off so I moved to sit on the edge of the prom in front of the beach hut, finishing my tea before I jumped down onto the beach to follow him (I couldn't see him properly from the deckchair).
As I sat there, one boy fired his super soaker at my back. His mum said 'darling, don't fire your gun at the mums' and he laughed and did it again. I turned and made a cross face at him and he did it again. I was then absolutely drenched front and back. So I shouted at him, really loudly.
His mum said nothing apart from the first 'darling ...' which he just ignored. I did shout a bit too loudly but the water was freezing and I really, really didn't want him to do it again.
The kid looked shocked but stopped. I apologised to his mum for shouting and explained that the water was really cold and it was a shock and she didn't really respond. Since then, I've texted to apologise again for shouting but she's not replied. Was IBU? Am I going to be a social pariah when school starts again?
