This ongoing thingy
This once a month for 3 months in a row. Is that with the same children? I would assume so because you have to meet the same child in order to build up trust with them, but if that is the case why do people who make occasional visits to schools (i.e. writers) have to be vetted as the likely hood of them meeting the same kids again and again are unlikely.
Of course it means that the writers have to keep track of all the children that they have met for the last 3 months so they can check that none of them could trust him/her. If only there was some technological solution to aid the tracking.....
