The anti-feeling - if such it is on my part - is nothing to do with her physical attraction - which is considerable.
It is her utter lack of anything approaching a personality that anyone can warm to. Similarly, as she showed on Countdown on a daily basis, she is a total stranger to the nuances of wit and humour - being unable to discern if Richard Whitely (who had neither) was being amusing or not - the answer was always 'not'. So they both exhibited the hallmark of the terminally humourless, the strained laugh - a weird titter in his case, a booking bray in hers - and neither knew what they were laughing at, but since the other was laughing there must be something funny there ... there never was.
That's my objection, although if I were young free and single, I would welcome an opportunity to bonk her into a coma any day.
