My dh has sprung it on me that he has the chance to go abroad for a weeks free holiday, so I reluctantly agreed only to have been told it's actually costing £200 and that he will also need another £100 for food, his only argument is that "yes but the holiday isn't costing me anything" he cannot understand that the food and travel is costing money. This argument has been going round in circles all night he cannot understand where I'm coming from, surely free means no cost ?
