Excuse me

We are buying some sweaters to our daughter in NL.
The method recommended by her is the following: I take a photo of her in each piece and then on the basis of the pics she takes the decision.
I pop the question: what if she just takes a look directly in the mirror?
From her look I conclude it was the Ultimate Evidence of Misunderstandings cross Generations. 
I say a quiet ‘sorry’ and back out of the changing room with my eyes downcast.

Blah blah blah

Our son (10) brings home his school report.

He: ‘To sum it up, I have received top scores from basically all subjects, except for ‘free discussion’, from which I got a 3 in a scale of 5.’

Me: ‘How come?’

He: ‘Some of my classmates receive better scores, but they talk about all kinds of pointless blabla, while I only speak when I have something to say.’

Me: ‘But when is this class? Morning or during the day? And what are the topics? And you have to prepare? And..’

He: ‘I have said everything about this subject.’

Me: ‘Ok, I think I get it.’
