They say that celebrities at the very top of their profession are the most genuine and modest.
They've made it, so they don't need to show off to impress.
And that is so true of Julie Walters, one of the greatest actresses that this country has ever produced.
A warm, witty, charming person that you feel you could happily chat to for hours about all sorts.
But also a true 'star' who combined a down-to-earth approach with award-winning quality at our special 'Audience with Julie Walters in conversation with Jenni Murray' event in London last night.
Special guests interested in supporting our charity were treated to an exclusive interview with Julie that covered her move from nursing into acting, links with Manchester, comedy partnership with Victoria Wood, preparation for roles in her acclaimed films and TV dramas and her family.
A fascinating interview that we never wanted to end.
It was an emotional as well as entertaining evening, with one of our patients also talking about her moving battle with cancer.
And I spoke about how the opening to the book 'One Day', which I've just read, resonates so strongly which the Christie job of working hard to give people 'extra days'.
'One Day' we will be able to give our patients 'all their days'.
And that's what this event was all about.
Trying to secure additional support for vital research.
And stars such as Julie and Jenni are helping to bring us closer to that day.
