I guess it depends who it is... I recently watched a programme on Neil Morrissey about how he went back to the care home where he grew up. He met with his childhood social worker and found out for the first time why his brother and he were put into care.
That was pretty interesting.
But I know what you mean when they waffle on about how hard they had to practise at their posh drama schools etc.
As they say on TOWIE: "Shut Up!!"
