That’s what I meant. If you believe drama can only be derived from conflict—and particularly if you also equate conflict with shoutiness—then characters have no option but to be unpleasant in one way or another. Their sole function is to provide drama, so there’s no room for someone simply to be pleasant. The last characters I can remember being generally decent, Hayley and Nigel, have both been written out; even Jill is now complicit in deceiving one of her own children. Paul was perfectly pleasant when he first appeared, but was subsequently reinvented as a controlling git. Stimpleton is on record as saying that Rob was rewritten on SOC’s orders; there was no sign of what he later turned into when he was introduced.1 A bit nosy, as has been remarked, but I always interpreted that as a “New Listeners Start Here” device.2
1It seemed obvious, to me at least, that after Paul was killed off Rob MkII was given some of his unused scripts.
2IIRC his first appearance wasn’t long after AmEx was launched, so I suspect they were preparing for an influx of new, younger, listeners, fresh from R4X.3
3After all, nothing thrills Da Yoof more than endlessly looped re-runs of Dad’s Army and The Navy Lark
