Ordinary folk bumble along doing their best. People who have worked in prisons, social work, the law, health visiting to name but a few, are more familiar with the dark side.
Blimey, that's a bit pompous, Iam
I live in a community that has witnessd two major and nationally reported serious crimes in the last fifteen years or so. I can tell you that ordinary folk do not just bumble along....They question, discuss, assist in enquiries, gossip (as all communities do) and speculate - because they possess a modicum of intelligence.
It's not convenient for the scriptwriters to have Ambridge folk involved in the Rob/Helen storyline so that's why Shula and others have been sidelined.
Kirsty, for instance, doesn't seem to have told anyone about the time she was flung out of BHC by Rob in a threatening manner. Ian and Shula have reasons for keeping their run-ins with Rob to themselves but Kirsty has nothing to hide.
It's not a bit like real life.
