My daughter (14) is undergoing a dental surgery.

Her little brother, Walter (10) is asking questions: ‘And what will happen to you?’

She: ‘I am going in – then tomorrow coming out, but with a swollen face.’

He: ‘What does “swollen” mean’? I don’t know this word..’

She: ‘I will look like a Snapchat filter’.

He: ‘Aaaaa, now I understand.’
