Almost vacation

Our son (10) comes home today, giving me an envelope from school. I ask him to open it, he starts to read it out:

‘Oh, it’s about vacation!!’

(Note: vacation in Dutch – ‘vakantie’)

He (surprised): ‘..Only they spelt it with double ‘c’ instead of a ‘k’..’

Me: ‘Hmm, could you show me for a second? …. Ah, I see… it is not a spelling mistake: the 1st ‘c’ in this word you pronounce as a ‘k’ in most languages..’

He: ‘Oh nooooooooooo!!!!’
