My dad thinks the calendar in the house is wrong. He sees that it's 19 August, but if there are no appointments or notes written on the entry he thinks the calendar is faulty,
Mum explains to him that they have no appointments on that date and then shows him the next date when there is an appointment or outing (eg 23 August). It doesn't register and he becomes stressed and angry towards my mum for not having the "right" calendar.
Any advice would be gratefully appreciated.
