AIBU to be absolutely raging that my child was taken to a park on a playdate and left there with his 2 friends for an hour with no adult supervision. The park was a 5-7 min walk from the house at which he was to have a playdate in. I had asked that my child did not go beyond the gate as he has just turned 8 and the house was on quite a busy road in the middle of a housing estate. The parent told my child not to tell me!!! My child returned home and told me older children in the park were teasing them and he was very subdued and out of sorts. For the record I am not a helicopter mum and am very measured and realistic but I cant help thinking anything could have happened.
