Regrettably I'm no exception, as I realised after watching this.
This Herald's article sums it up:
The answer is that only the pretty are expected to achieve. Not only do you have to be physically appealing to deserve fame; it seems you now have to be good-looking to merit everyday common respect. If, like Susan (and like millions more), you are plump, middle-aged and too poor or too unworldly to follow fashion or have a good hairdresser, you are a non-person.
Thank you, Susan Boyle.
For making me realise my hypocrisy.
