At DS swimming lesson watching from the side there is a boy (not in the lesson in the general swimming area I would say approx 9/10) he appears to be unaccompanied. He has white shorts on they can't be official swim shorts as they have gone completely see through! To make it worse he keeps getting out and walking around the side so there are a lot of people who can see. When the lifeguard passed me I told him the situation and he said there was nothing he could do. Surely he can't just let the poor boy continue he seems completely oblivious bless him. Wwyd?
