On holiday with DH and DS 8. I had to come back from pool early as had to have a chat with someone re a job interview. DH supervising DS at pool on small water slide and water play area. They come home saying they had a brilliant time but DS hurt his head. Why? I asked. “Well, when I was coming out of the waterslide backwards, I fell and hit my head of bottom of pool” ( not deep! And a shortish slide) At this I was horrified. A) why was he going down a water slide on his back headfirst… ? Totally not allowed. Apparently I’m ‘boring’ for suggesting he should only go feet first and DH deserves a medal for all the supervision he’s done. FYI I am significantly bigger breadwinner and job interview important. AIBU?
