I'm interested to hear your views on this. 13y/o ds was waiting for me in the first car park, he saw some younger boys destroying a sapling and walked over and told them not to damage it. The boys ran off to tell their Mum who then came and told off my ds. She asked him where it said they shouldn't damage the trees so he asked where it said they could? She then told him she wasn't going to argue with him and it wasn't his place to question her parenting.
Personally, I'm rather proud of ds for saying something to the boys and have always instilled a respect for nature in my children. I told ds I thought he did the right thing. Bg the time I arrived the boys were booting their football at other people's cars and it struck me that their mother was rather ineffective at controlling them.
So YAIBU children should be allowed to damage trees in the forest, your ds should have minded his own business
Or YAINBU it is wrong to let kids damage trees and your ds is a hero amongst teens
