Me : What would you like for tea tonight?
H : spaghetti bolognese!
Me : We don’t have any spaghetti, I need to buy some – shall we have soup instead?

Me : We don’t have any spaghetti. We have carrot soup though.
H : I don’t want carrot soup. I want spicy soup.
Me : I can make the carrot soup spicy?

Me : (phew) Okay, carrot soup it is.
