I'd like to think it was innocence, but as she's a trainee woman she's probably already learning to be 'clever' like wot us boys never got taught and why women are always cleverer than us.
When my stepson was 7 he said 'I don't think I need to go to school any more'. 'Oh, why's that?' 'I can't think of anything else that I don't know.' He wasn't being clever, though. He was being stupid!
Aaah,
Your niece comes from a famous family Garry!
I remember seeing your initials on a huge number of pillar boxes when I lived in the UK.
They had a little crown on top, I suppose that's due to your interest in the Air Ministry.
