To protect children, exuses are not suficient.
Right now; parents, schools, children homes, responsable in public places and streets; must explain - inform children about such kind of contacts aren't correct, arent' their mistake (often there are feelings of quilt), are no games and can only harm.
It is also important teachers are talking openly about such sick behaviour in class rooms to break the shame and fear in which harmed children are dwelling.
Also a telephone number, where children can talk without fear should be given.
The sun shines impartially.
