To be fair, I think sensitivity and seriousness are thin on the ground for all characters in The Archers. Can't think that any of the principal members of the Faaammmleee are weighted down with these qualities. And even though it's stretching it a bit, if there is one character that most consistently shows these qualities, I'd say it was Clarrie.
But TA is not particularly good writing, it just tunes into a need for narrative and habit! And very effectively too. Also, I think we all quite like being in our little TA tribe, don't we? or we wouldn't also be on this thread. (I am wasting sooo much time on Mumsnet these days...it's shocking, it really is.)
