Younger people would certainly turn out in greater numbers for celebrities
Actually, I'm not sure that you're right.
So, a girl group or a young male rapper rock up to visit a primary school and try to show an interest in something other than themselves, how many fns would turn up?
Star struck teenagers, missing the point of the visit entirely?
If the Duchess of Cambridge turns up, people are interested in what she has to say and know that she is more interested in the children and their education then she is in herself.
There are exceptions, eg Marcus Rashford but his interests and excellent contributions are not as wide ranging. Perhaps one day.
Perhaps that says more about your age and social position
I never told them that you're in fact a Countess, maddyone, honestly!
