My son got up by himself in the night, let a strange man in from the garden, let him wander round the house and went off with him for hours. No DBS check or anything. He told me they went riding on a motorbike (no tax or insurance) and them they flew through the air together. Then they went to a party with loads of food I hadn't vetted and a crowd of men I don't know who were dancing and drinking alcohol.
He's now woken up and very upset because his friend seems to have disappeared leaving only his scarf and hat.
AIBU to be worried and upset?
