I just wanted to get some opinions if I'm overreacting. My DH’s brother suggested that they all go camping in France for the weekend as he’s done it before. Explained how easy it was to book campsites. He then suggested that my DH comes with our boys 5 and nearly 7. So they set off yesterday along with DH’s brother’s teenage sons 18 and 16 and their other brother. I got a message from DH last night saying the boys are sleeping and they arrived safely. This morning I get some photos of a beautiful view of the beach. They set up 3 tents on the beach and slept there. I don’t know any other details as to why but I’m really annoyed. I feel like agreed to the boys going to campsites not to sleep on the beach. Am I overreacting? Do people normally do this? Is it safer than I imagine? AIBU?
